LR Classic have started to crash when I export photos, it's a bit strange since the LRC UI keep on running but I get a crash dialog and a stack trace. So I guess that the export is not only done in a separate thread from the UI, but on a completely different process. Does this happen for just me or are there others who have the same problem

The top of the crash log reads

Code:

Sequoia is a recent update from Apple. I’m not sure Adobe has announced support for Sequoia. It is possible that this could be your problem. Are you using a Silicon or Intel Mac?

It might help Adobe if you report it as an issue. I am sure there will be bugs in MacOS 15 that will require a decimal update.

Intel, a 2018 Mini with a basic config ... so I can't take advantage of all the features in LR

This has happened for a while, I'm not sure if I had problem before I upgraded to Sequoia or not. I'll send some info to Adobe the next time it happens.
 
In your Export dialogue, do you have something specified in the Post-Processing section, at the very end? If so, try running without specifying that.

Since Mac OS 14.4.1, LR has had issues with Intel Macs with certain GPUs. Next troubleshooting steps:

1. Do the LR menu command Help > System Info and copy/paste the entire contents here so we can see exactly which versions of hardware and software LR thinks you're running and important LR options that are set.

2. Set Preferences > Performance > Use Graphics Processor to Off. Do you still get the error?

Most likely, your export is running a post-processing action that invokes a child program, e.g. a plugin like Metadata Wrangler or JPEG Mini. The LR SDK for plugins has a bug that only seems to occur on Intel Macs for which reports are trickling in. See here:

You might want to follow that thread for updates.
