LRC keeps crashing even after uninstall/reinstall, gpu turned off/kept on, restarted computer

[dana48554131]

This is just happened recently on my last 3 catalogs where it will randomly crash when already have made adjustments. I will create the catalog on my 2019 mac pro and apply masks, presets, then have my editor take care of the toning, adjustments, ect on the M1 which everything is fine (ran on a network but in the same office), then when bringing it back to my computer it becomes glitchy after an hour or so of editing. I have tried all of the steps (uninstalling/reinstalling/turn off gpu/restart computer) but this keeps happening. It will go if I am doing major changes and it will go if I am just looking and doing very lite tweaks. Any help would be fantastic!

Hey, @dana48554131. Welcome to the Lightroom Classic community. I'll help you figure this out. What version of Lightroom Classic are you working on?

(ran on a network but in the same office),- Is the Lightroom Catalog kept on a network drive?

Please keep the catalog on the internal drive only. Check this to learn more about this: https://helpx.adobe.com/lightroom-classic/kb/catalog-faq-lightroom.html
You can try keeping the source images on the network drive & make Lightroom write the settings to an XMP metadata sidecar file. Go to Edit > Catalog Settings > Metadata > Automatically write changes to XMP.

Thanks!

Try logging into another Mac user account (you should make a new one); still crashing? 
Try starting up in Safe mode (hold down Shift Key when booting*), still crashing? 
You might want to try running a free utility like Onyx: still crashing?

* How to start your M1/M2 Mac in Safe Mode
On your Mac, choose Apple menu () > Shut Down.
After your Mac shuts down, wait 10 seconds.
Press and hold the power button until the startup disks and Options appear.
Press and hold the Shift key, then click Continue in Safe Mode.

Try fixing permissions by running Disk Utility (Disk First Aid) or, again, using Onyx.
