What's going on with this Photoshop?

Thank you.

This happens when I try to edit a 3D element. If I restart Photoshop, the issue goes away until I start editing 3D again. I turned on the "Deactivate Native Canvas" option in the settings, but it didn't help.

Please try to disable the option to "Use Graphics Procesor" from Photoshop by going to Preferences, then Performance. Once done, quit & relaunch Photoshop to check if that helps. 

If you're unable to access Preferences and PhotoShop crashes before that, please go to the location C:\Program Files\Adobe\Adobe Photoshop 2021. Then rename the Sniffer.exe to Old.Sniffer.exe and try launching Photohsop again. 

If it helps, you can check out the steps suggested here:  https://helpx.adobe.com/photoshop/kb/troubleshoot-gpu-graphics-card.html 

If the issue persists, you can try to reset the preferences of Photoshop using the steps described here: 

Preferences in Photoshop (adobe.com) 

Please backup your settings before resetting the preferences. You can check: 

Migrate presets, actions, and settings (adobe.com) 

Another try it to turning on the option »Deactivate Native Canvas« (Photoshop > Preferences > Technology Previews) and restarting Photoshop.
