Hi there, I’ve been struggling with a recurring bug in Lightroom Classic (v14.3.1) related to the AI-based Remove tool and the “Update AI Settings” prompt. Here’s what’s happening: I’ll use the Remove tool on an image and allow it to finish processing.I’ll then move to another image and continue editing.When I return to the original image a few minutes later, the removed object has reappeared.A triangle with an exclamation point shows up, prompting me to “Update AI Settings” — even though I’ve already done this previously.This cycle keeps repeating, and edits don’t stick.     What I’ve tried (and confirmed):  I’m running Lightroom Classic v14.3.1 on Windows 11.GPU settings are set to “Auto”, but I also tried manually enabling full GPU acceleration.I’ve restarted Lightroom, reinstalled Lightroom, and even paused cloud syncing.I’ve waited for the AI edit to finish before moving to another image.I cleared the masking cache by deleting the Helpe

# Environment- Mac: MacBook Pro 14" 2026, M5 Pro (18-core) (identifier: Mac17,9)- RAM: 64 GB- macOS: 26.5.1 (build 25F80)- Lightroom Classic: 15.4.1 (latest)- Power: AC connected, High Power Mode enabled (powermode 2)- Catalog: freshly created; source files and export destination both on internal SSD- Previous machine for comparison: MacBook Pro (M1 Pro) # SymptomDuring export, total CPU utilization plateaus around 50% and exports are much slowerthan expected. Using powermetrics, I confirmed that while exporting, the P-cores(P0 cluster) are ~100% active but locked at roughly 2.4 GHz (2304-2652 MHz),never boosting above 3 GHz. The P1 cluster stays mostly idle.Measured comparison against M1 Pro (same photos, same export settings):- Export: 92 s on M1 Pro -> 70 s on M5 Pro (only ~24% faster)- AI Denoise: 9.5 s on M1 Pro -> 4.5 s on M5 Pro (~2.1x faster)GPU/Neural Engine-bound tasks like Denoise scale as expected with the new chip,while the CPU-bound export barely improves.

I’m a heavy volume shooter, I see daily that Lightroom Classic will fail on HDR merges. No errors, no crashes, LRC will just hang indefinitely on “Merging HDR….”.  You can use the program normally. The only way to fix it is to terminate LRC, re-open then merge the stacks again. I notice it usually hangs on large volumes, say 30-40 stacks at a time. 

Latest LRC, during a session right click ceases to work as do all keyboard shortcuts. on macOS Tahoe with an M1 Max. This happens hourly. 

After upgrading to Lightroom Classic 15.4.1, I find that the Before image in the Develop module is often blank.  I have undertaken all of the possible troubleshooting steps with no success.Downgrading to 15.3.1 solves the problem in a new catalog but if I then upgrade that new catalog to 15.4.1 the problem returns.Is this a known bug???

I am truly flummoxed! I’m having major issues printing from Lightroom Classic and I’m wondering if it is due to the update to v15.5. It takes about 5 minutes to print one image. In addition, color is completely off now, and it was fine just a few weeks ago. I’m using a Mac, OS Tahoe version 26.6.1 … and that is a recent update as well (so is is double trouble?). I am printing using my Canon Pro-1100. I print on a variety of Red River papers, and use color profiles provided by Red River. Prior to the update things worked quite well. When I print from the Mac Preview app rather than Lightroom the colors are correct and it prints at a normal speed, which is why I’m thinking it might be a Lightroom issue. 

LrC 15.4.1. MacOS 15.6.2  When LrC is opened for a longer period of time the upper tool bar locks up. I can't hide LrC or access any other tools. I've had to force quit LrC a few times.

Applying Quick Select or keystroke ‘B’ to images in the list of “Deleted Photos to Remove” from a Publish service fails to select images. Only by mouse-selecting to activate the “Photo is in Quick Collection” icon will said image be added to the Quick Collection.  Multi-selecting the “Deleted...” photos is often necessary when metadata for many images needs to updated so that they remain published.

GPS Coordinates bug. When CTRL-Click selecting multiple images on Map view, they all inherit the same GPS coordinates. Restoring coordinates requires reading file metadata.

quando faça a exportação das minhas fotos em Raw no meu Lightroom (Lr), fica aparecendo uma mensagem que não está sendo possível pois não encontra o tamanho original em nuvem, e está assim a algum tempo, e por mais que meu armazenamento não esteja cheio  fica aparecendo assim. vou deixar aqui o print da mensagem, eu utilizo o computador e o Ipad para trabalho nas imagens, e outra erro e que o uso de IA de um aparelho para o outro não se atualiza sozinho e tenho que ficar perdendo tempo atualizando manualmente. 

 SUMMARY=======Importing a large image (approx. 143 MP) into Lightroom Classic crashes theapplication 100% of the time on my machine. The same crash occurs on threedifferent LrC versions, including after a full downgrade, so it does not appearto be specific to one build. Smaller images import fine, so this is asize-dependent failure in the import path.CRASH SIGNATURE (identical across 10+ occurrences)==================================================Faulting application : Lightroom.exeFaulting module      : ntdll.dll (10.0.19041.7548)Exception code       : 0xc0000374 (STATUS_HEAP_CORRUPTION)                       0xc0000005 (ACCESS_VIOLATION) on some occurrencesException offset     : 0x00000000000ff509  <-- identical every single timeWER Sig[7]           : PCH_08_FROM_ntdll+0x000000000009E164Adobe crash reporter stack, top frames:  [0] mems...  (memset / memcpy family)  [1] RtlAllocateHeap  [2] RtlAllocateHeap  exception = EXCEPTION_ACCESS_VIOLATIONWindows subsequently applied Fault

OK. Now I see what happened, so I’ll start over. I’m hoping that someone has an idea for a fix for this.Re: LRC 15.4.1Running painfully slow. A little history: I’ve been a Lightroom user for over 10 years, along the way Lightroom would bog down once in a while, but it always seemed to function good enough, until it became unacceptable. I was due for  a new system so in 2012 I purchased a new XPS8500. Things went well, but the day came where Lightroom slowed to a crawl again. Fast forward to 2018 when I purchase my present system. Specs:Dell XPS8950Win 11 Pro32GB DDR4 2266 Mhz1TB SSD2TB 7200 rpm HDD NVIDEA GeForce GTX 1080 w 8GB GDDR5X Graphics MemoryBDRE DriveWith this system all problems all Lightroom problems vanished and I could multitask with several photo applications along with Lightroom with no problems.

When opening it shows a box.  “Lightroom has encountered  issue updating AI edits.  Future AI edits may not be saved and could be lost.  Please contact Adobe customer support for trouble shooting.click open recent under catelog the only catelog that comes up is LR catalog.Ircat. Under Manage Catalog, it shows LR catalog.Ircat is located under One Drive.  That is not one of my catalogs and I do not use One Drive.  It gives a choice to Remove All which I haven’t done yet.

I am currently running version 15.5 of Lightroom Classic.  I have had an issue over the past few versions where while in the Develop Mode and trying to  enlarge or magnify the image during editing the screen goes black.  I can only get the picture back by selecting the fit to screen option, but I am unable to utilize a zoomed in version of the image for more refined selections or any other type of editing.  Is this a common error or after all these years am I doing something wrong?  Any help would be greatly appreciated, thank you.

Can i use Lrc both on pc as well as mobile?

Hi everyone. I am posting in this forum as Lightroom is what I’ve used, and I cannot find a support email address to ask Adobe directly.I subscribe to a 1TB/month cloud storage, as well as to the Creative Cloud monthly applications package. I am cancelling both services as I haven’t used them much in years. However, there are warnings upon cancelling that photos may be lost if I cancel. I’d like to not lose any of my photos, as I may want to pick my editing back up at a later time. Does anyone know the following:If I cancel my services, if I re-subscribe later, will all my photos be there again in my photo library, or would I be starting from scratch with an empty library and need to re-import everything? If the photos would still be there - will any edits I’ve made still show up, or no? Also… my mind boggles with the locations of all of my photos - when I first started they all lived on hard drives nicely organized, but once services started switching to cloud I became very confused w

Hi.Frontline chat support refused to help me. I have an active Photography plan subscription. My 2015 MacBook Pro is limited to macOS 12.7.6 Monterey and Creative Cloud won't let me download older versions. Can a staff member please provide the official direct installer link for Lightroom Classic v13?Thanks.

I am having a serious problem with Lightroom Classic 15.4.1 on Mac.Lightroom displays the following error on startup:“AI Edits Storage Error – There was a problem updating AI edits in Lightroom. Future AI edits may not be saved and may be lost.”The problem is affecting AI edits across different imports/catalogued photos.Examples:I use Imagen AI and its Background Mask beta feature. Lightroom shows that the mask exists, but the actual masked area is missing. When I click the AI update button, Lightroom recalculates the mask correctly. I can then edit the mask, for example by changing exposure. After leaving the photo and returning later, the actual mask selection has disappeared again, although the mask entry itself is still present. I also used Lightroom's AI Remove/Generative Remove tool. The removal looked correct initially, but later the removal was gone again. Updating 10 images in bulk takes a long time, but the AI masks are still missing afterwards.Lightroom has also become extre

I’m experiencing a display/rendering problem in Lightroom Classic on macOS.When Lightroom Classic is in Develop on my primary display, the image shown on the Secondary Display immediately becomes noticeably lighter/washed out when I select it. This happens in both Grid and Loupe view on the Secondary Display.The same photos display correctly in Library and Print, and the problem occurs on all four of my connected displays.Expected: The Secondary Display should show the same appearance as the photo in Library/Print.Actual: The selected photo becomes visibly lighter/washed out only when the primary Lightroom window is in Develop.I can reproduce this with a brand-new catalog and an untouched JPEG or RAW file. I have also tested with GPU disabled, reset Lightroom preferences, purged the Camera Raw cache, and updated Lightroom Classic to the latest version. The behavior remains unchanged.System: 2019 Intel iMac, Radeon Pro 555X 2GB, 32GB RAM, macOS 15.7.7.

I used to edit photos in the FIT option. and Zoom when I required to edit a specific area. I was not an issue till now. But happened to be like shifting the color/exposure when I trying to zoom. This affects the final export as well I am seeing different output that I see in the fit  options. I tried by changing the GPU off and On but resulting same. 

Hi all.  I'm SUPER frustrated right now, and feel like I've been chasing my tail.  And I think that there just isn't a solution for my problem, that it is a bug in the software, but I'm really hoping that is not the case.So, when I export my RAW files as jpegs, my noise reduction settings are completely ignored, and the images turn out extremely grainy with a lot of noise.Just to clarify... I understand high ISO, I am NOT applying any sharpening or sharpening output settings, and my images look great (with NR) in both the library and develop modules.It is only when I EXPORT that they become a grainy mess.So, after spending hours researching what could be wrong, I discovered that if I export the image with ANY kind of resizing, the NR DOES apply.  It is only if I try to export it in its original size that it the NR settings are not applied.Trouble is, I really want to export all my images in their ORIGINAL size.  I do not want to make them smaller in any way, as I am

Description of Issue:Lightroom Classic freezes the photo preview after using AI Denoise combined with Sync across a batch of high-ISO photos. Once the bug triggers, no slider adjustment updates the preview anymore - only the histogram reflects changes, not the actual image.Lightroom Classic Version Number:15.5OS Version Number:macOS 26.5.2Camera Model:Sony A1 II / A7R V / A7S IIIStep-by-step Reproduction Instructions:Import a batch of high-ISO photos, some already partially edited. Select one photo and apply AI Denoise at approximately 30%. Select all high-ISO photos in the batch and Sync settings from the denoised photo. Navigate to the first photo in the batch (one that had edits applied prior to the denoise sync). Attempt to change any slider on that photo.The Expected Result:The photo preview updates in real time to reflect the new slider values, as in any normal edit.The Actual Result:The photo preview is frozen and does not update regardless of slider changes. The histogram does

SummaryImporting photos in Add mode (files already local on a fast NVMe volume, no copy/convert) is extremely slow. CPU utilization spikes for 1–2 seconds, then the application goes idle for 5–10+ seconds, repeating in a cycle. During the idle gaps the Lightroom window intermittently reports Not Responding. Per-second process tracing shows the import pipeline is running with a median of 2 active threads while the rest of the machine is idle.

I can't open any of my LRC catalogs.  I get message "AI storage error."  Tried to find the Data storage file.  Supposed to find it in "Help>system info>library.  Window shown after these steps shows no "library."No problem opening catalogs when I move my master HD to my laptop. Laptop is running LRC 15.4. Mac Mini is running Tahoe 26.3.1 Desktop is running LRC 15.5 release.  Should I re-download software on desktop mini? 

On my laptop, when I highlight a folder>press file>export as catalog I get the dialog box but I cannot choose where I want it to be exported. After a bit lightroom says it must close and offers to report the issue. This function worked a week ago and works on my desktop. Please help I need this function.Bill
