LR Classic V12: LR Crashes After Cropping Image

[Glenn Hurse]

Upgraded to V12 in tha last 36 hrs. LRC on Win 10 21H2

1st use  :: able to use most functions without issue.
BUT on my 3rd image, cropping and LR locked up, could not crop and could not exit Crop mode - LR was non responsive. 
Forced close of LRC, restarted, immediatly could not even open an image, CPU at 100% Forced Restart of PC.
After restart, LRC opened to solid 100% usage on 4 cores of the CPU (30% of total CPU) and was non responsive for 5 mins.
Restarted LRC:: Next start same issue my LRC opened and dropped to nominal CPU usage after a minute.
Managed to edit and Crop 2 images.. 3rd image.. LRC froze on exiting Crop mode.
Restarted PC, cleared LR cache, and checked the catalogue.
confirmed now consistently CPU 100% on 3 cores (of 12)  at start for a solid 5 minute. 
No issues with basic editing, except cropping, as many as 20 images at a time, BUT, as soon as I attempt to crop 3 images.. Freeze..
I consider the program FUBAR if it is incapable of responding within 10 minutes
I am not happy with the prospect of rolling back to v11. But if I have to I will.

Try each of these troubleshooting steps in turn:

1. Set Preferences > Performance > Use Graphics Processor to Off.

2. Update your graphics driver by going directly to the AMD web site. Your current driver (30.0.21017.1000) isn't the latest (it's from 5/16/2022).

3. Try resetting LR's preferences:

LR sometimes soils its preferences file, and resetting it can fix all sorts of wonky behavior. That article explains how to restore the old preferences if resetting doesn't help.

Thank you very appreciated. Fixed

I thought I had updated the drivers, forced the update and it applied and LR failed first attempt.. but it has fixed a jitter that had crept in on 4k video editing..
The Preferences appears to have been the issue.. worked through a number of images and it is snappy as on the process.
 Added the preferences to my list of SOP fixes..
I will repeat.. Appreciated.. Thank you for your time

Cheers

Glad you got it resolved. It's unfortunate that Adobe has never fixed the core design issue that causes preferences to get corrupted so often.
