Lightroom Classic

My Lightroom Classic just updated to the latest version (13.0).  When I exit, rather than the option of delaying writing XMP, it now says I should wait until it completes. The first time, I let it complete in case the delay was due to the update.  I didn't time it, but it took several minutes.  I went back in, and made minor edits to two images and then exited.  It's been over 5 minutes, and it's only up to 14%. Why has the message changed to say you should wait?  Why is it taking so long?

I even went back and looked at a JPG I exported out of Lightroom earlier this year and that image had a hefty resolution of 5000x4000. No problems there! I’m not sure what happened! help!

 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

Everytime I open lightroom classis now and try to use my pixieset plugin I get the error code #1000 "Connection failed, please check your internet connection and try again". I have strong internet connection so this isn't the case. I am using Lightroom classic v 14.5.1 on Windows 11 and recently switched internet from spectrum to fiber, not sure if this has anything to do with it. I have removed and added the plugin several time as well. Would appreciate any insight, this has been very frustrating!!

Once a photo is loaded from my library, after hitting develop, pictures have color splotches on them that makes editing them impossible. This seems to have started on or about 7/20/26.Original:In Develop mode without starting any editing (note: I have restarted my computer since the issue started): 

I encounter an issue with the latest update (V11) on shortcuts to assign a color label (6,7,8,9).Those shortcuts won't anymore assign a color label, it will now only remove the color label. The shortcut "Assign a color label and go to next photo" (Shift+6 to 9) still work well as previously.Please fix this adobe, my culling speed depend on it. Thanks in advance,

·  Title: LrC 15.4.1 UI Issue:  Closing Remove Tool leaves gray panel area; fails to redraw Edit/Basic panels. ·  Product: Adobe Lightroom Classic v15.4.1 Release (Camera Raw 18.4) ·  OS: macOS 25.6.2 ·  Description: In the Develop module, using Solo Mode with the right panel visible, activating and then closing the Remove (spot removal) tool completely breaks the right panel interface. The panels vanish into a blank, dark empty column. Global panel keys (F8, Shift+Tab) and top menu toggles fail to restore it.  Workaround: Clicking the Edit icon (sliders) manually, or toggling Crop (R) or Masking (M) or Red Eye Removal icons on and off forces Lightroom to redraw the UI, successfully bringing the Basic and edit panels back.   Exiting the develop module to the Library module, (G or E) and then re-entering the Develop module (D) will also bring back the Basic and edit panels. ·  Camera model:  N/A ·  Steps to Reproduce:Open Lightroom Classic 15.4.1 in Develop module with Solo Mode active.

Hey,I’m stacking in PS from LRC, saving works fine, flagging, color label works fine. During the same session, these files disappear from LRC. They’re on the disk. I can’t import them, the import module won’t “see” them.

Hi,I recently switched from a MacBook to a Windows PC, and it seems to me that Lightroom Classic is not working properly — although Adobe support says everything is fine.The program runs very slowly. When using masks, there is a noticeable delay in the preview, and the image appears to jump or refresh. I’ve attached a video below showing the issue:https://youtu.be/Rdp1xHr3LAk?si=JiAgedctehGnfyoIIs this normal? On my MacBook M1 I never had any problems with smooth performance.I also noticed that when Lightroom Classic is open, the entire computer seems to slow down — even moving a Chrome window feels laggy and stutters. When the program is closed, everything becomes much smoother again.Here is my computer specification: AMD Ryzen 9 9950X3D ASUS Prime X870-P WIFI 192 GB DDR5 5200 MHz RAM RTX 5080 16 GB 2 TB Samsung 990 PRO M.2 (up to 7450 MB/s) 4 TB Samsung 990 PRO M.2 (up to 7450 MB/s) 4 TB Samsung 990 PRO M.2 (up to 7450 MB/s) 1200 W BeQuiet modular PSU Fractal Meshify

Product: Adobe Lightroom ClassicUI language: Polish (Polski) — issue also affects English source copyOS: Windows 11Lightroom version:[paste from Help → System Info → Copy]Steps to reproduce:1. Library → select any photo → File → Export (Ctrl+Shift+E)2. File Settings → Image Format: JPEG3. Enable “Limit File Size To” → set to 5000 K4. Click ExportActual result:A dialog appears. In Polish UI the title is “Aktualizacja limitu rozmiaru pliku” and the message reads:“Jeśli obraz nie może osiągnąć limitu, zostanie on eksportowany do minimalnego możliwego rozmiaru pliku.”The English source text (approximate) is:“If the image cannot reach the limit, it will be exported to the minimum possible file size.”Problem:Both wordings are misleading. “Minimum possible file size” strongly suggests Lightroom will crush JPEG quality to the smallest file (e.g. tens of KB). That is alarming and contradicts what users expect from a paid subscription.What the message should describe is the opposite scenario: wh

I purchased Lightroom Classic v15 but recently it has been crashing all the time. Was recommended to download the latest version (15.4.1) but now it says I have rebuy the program. As I already purchased it don't want to pay again. how do I get back to my original working version?

Description of Issue:Merge to HDR stalls (application unresponsive, beachball) when merging exposure-bracketed images on 15.4.1. Another user in an original 15.3 thread reported this resolved after updating to macOS Tahoe 26.5. I am on macOS Tahoe 26.5.2, a newer build, with a fresh OS install, fresh Creative Cloud install, and a brand-new catalog, and the stall still occurs on 15.4.1.

I moved a folder from one hard drive to another and Lightroom is throwing me in a loop. I’m at a loss, I don’t know what to do here! This makes zero sense I’m going in circles.   

As the title says the folder where my Lightroom catalog is stored only shows the folder 0 to 9 and A to F. In these folders there are seperate folders (like 0A2A). Is there a way I can rebuild/restore my catalog?  It is not showing any .lrcat / .lrdata files.
