Lightroom Classic

 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

Since I updated to MacOS 14.6, printing from Lr Classic to my Epson SCP800 has beeen a nightmare. The printer driver seems to have become completely unreliable.    1. When I select a profile in Lr, the printer driver has color matching set to Epson Color Controls, and not (as it should) to Color Sync. Sometimes the driver opens with Color Sync correctly set, but then changing any other setting (eg, paper type) causes it to revert to Epson Color Controls.   2. When I make changes to the print settings (eg, changing paper type) and save a preset, the change is not present in the preset. This problem does NOT seem to occur when using the print driver from Apple Preview.   I have -- reinstalled the Epson drivers -- deleted and readded my printer -- deleted my Lr preferences (but I'm confused about this because moving the com.adobe.LightroomClassicCC7.plist file out of ~/Library/Preferences doesn't seem to change anything in my Lr setup, even if I restart my machine

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. 

Whenever I try to apply a preset, any preset, this message pops up. “Downloading AI ModelsSome AI Models are downloading. Please try again later.”There’s nothing wrong with my internet, or disk space or anything really. It literally just started happening after an update I did (v15.3.1). I’ve uninstalled, reinstalled a few times, same thing. I can’t apply any preset, but lightroom can still function properly as normal. Can anyone help? 

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.

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

I am on Windows 11 Pro and I have the latest Creative Cloud with PS and LR Classic, Nvidia 2060S with the latest drivers. This error started appearing a couple of months ago. I start Lightroom, never mind if I open the catalogue or click the icon, and it takes 20 minutes to pop up. Task Manager shows it’s running, but it takes 20 minutes to show up.

In 15.4.1 I have found that in Lens Blur the Blur option of Brush Refinement seems broken.  Using it does the same as the Focus option.  Anyone else noticed this?I am running the Mac version.

Since going to the 15.5 release, the Masking tools are not working correctly.  As with the attached screenshot, though there is clearly a subject, the Subject mask cannot find it.  I tried with several other photos and got the same results (on equally obvious subjects).

since updating to 15.3, I’m finding that Lightroom Classic is quickly hitting a memory leak and freezing or crashing.  I’m processing RAW Canon CR-3 files, often adding AI object removal, and synchronising my edits across groups of photos (including masks, AI object removals & colour grading).  I find that I can only run for approximately 30 - 60 minutes before I start to encounter memory issues and either the app pauses (and doesn’t come back to life) or crashes altogether.  I keep getting error messages telling me that my system has run out of memoryThis has only been a problem since updating to LrC 15.3 a few days ago.system tech specs: MacBook Pro (16-inch, 2021)Apple M1 Max64gb ramMac OSX 26.4.1
