Photos Unresponsive After Using Masks in LR Classic

[Roman Porechin]

1. When I create a mask, whether it's radial or linear, it doesn't matter. Sometimes it works, but other times, after creating a mask and trying to change any setting like Exposure, the preview photo on the left panel turns gray (see screenshot 1). Then, nothing works for that photo.

2. When I click on another photo and then go back to the problematic one, it doesn't show up at all. However, in the preview photos, both in the left and bottom panels, I can see the photo with the applied mask and settings, but the actual photo itself doesn't work (see screenshot 2). After that, the photo seems broken, and I can't do anything with it.

This issue seems very random. Once it happened when applying a preset, but usually, it occurs when using masks. I tried reinstalling the entire Lightroom Classic, but it didn't help. Then, I reinstalled it, removed the settings, and rebooted my PC. When I opened Lightroom, it asked to update the catalog, but even with the new Lightroom and an updated catalog, I still have this issue with random photos from different folders.

I have been using Lightroom for several years on a daily basis, so it doesn't seem to be related to my PC (Win 10, 8GB RAM, Nvidia RTX 3070, SSD). It really seems like a bug. I have this issues since yesterday (01.10.2023)

Found a solution which is turning off the Graphics Processor in Preferences > Perfomance. 

Or at least to switch off "Use GPU for image processing" if you have this option. 

Nvidea driver is up to date, so not sure if is it Nvidea issue or compatibility in the LRc

1.  Your attached screenshots never load, gave up waiting. Please use the Insert Photo button instead of the Attachment butto.

2. Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.
