LR 13.5.1 hanging up
I've started having issues with LR 13.5.1 (or just before). When I change screens or focus away from LR to another app or file on the desktop, when I return to LR, it has a scrim/screen over the image and the program is hung up, with the Windows scrolling wheel showing. I have waited up to an hour and it never reloads properly. This will happen with a small catalog of a few hundred and with large ones with thousands of images. It can also happen when I change between work areas of LR itself. I have checked the Task Manager, and LR is using maybe 50 - 60 % of CPU and around 10 - 20 GB (of 128 GB) RAM. The only way out of this is to crtl-alt-del to Task Manager and kill the instance.
I've been using the same machine for almost four years (AMD Rythen Threadripper 3960x 24-core) under Win 10 and moved to Win 11 a few months ago, but this problem started only a few days ago. No new plug-ins or changes to settings. Any suggestions would be greatly apprecaited (I use LR about 4 - 5 hours a day, and this is a real deal killer.) Thanks for any suggestions.
