Lightroom Classic 13.5.1 Freezing During Export

[daners1212]

For the past 3 weeks, I've had an issue where Lightroom Classic will stop in the middle of an export and give me an error.  The app doesn't close, but the export stops and the "Problem Report for Lightroom Classic" pops up.  This is what the report says:

And a screenshot (below) of my Lightroom Preference settings.  I've been on chat with Adobe a ton of times over the past few weeks and we've tried the following: uninstall/reinstalling Lightroom Classic, trying older versions of LrC, changing permissions on Adobe folders, resetting LrC preferences, disabling the GPU on export, disabling the GPU completely, exporting to different hard drives, exporting from a test user on my mac, updating macOS, exporting in safe mode, etc.  Nothing seems to help.

The amount of time/images it takes for the error to occur varies.  Sometimes I can export 100 images without it stopping.  Sometimes it's only 4-5 images, then I get the error.

Adobe mentioned that there could be an issue with Intel i9 and AMD with the new version of LrC.  Just trying to see what else I can try - I really don't want to have to buy a new mac since this one is only 3 years old 😞  Thanks in advance for any insight you can provide!!

Thank you for reaching out and sharing all these details. It really helps us gain a clearer understanding of what might be happening faster. 

Which version of Lightroom Classic did not have this issue? ^CM

[daners1212]

I'm not 100% sure if I had updated from 13.4/13.5 to 13.5.1 before this issue started, but we tried installing older versions once this export issue started - and even the older versions were crashing 😞

[CMass]

Thank you for the update. Have you seen a way to send a crash report at all? The team is asking if you can submit a crash report and PM the email address you enter. 

[daners1212]

The Problem Report for Adobe Lightroom Classic send directly to Apple, I believe.  I copy/pasted the report and am attaching it here

Following is not the cause, nor solution to your problem, just an observation of an issue that will cause you some performance issues in the develop module. You have the Adobe default of 5 GB for Camera RAW CACHE limit. Even Adobe in documentation states that is too low and to increase to at least 20GB

Did this issue start in coincidence with your upgrade to Mac OS 15?

What is your drive configuration? Are you exporting to a different drive than before the issue?

[daners1212]

No, it started while I was still using Sonoma - prior to updating to Mac OS 15 Sequoia.  I recently upgraded to Sonoma in hopes that it would resolve the issue... which it didn't.

I've always exported to my Mac desktop and haven't had any issues doing so until early September.
