I am having very similar problems to this post which never reached a solution from what I can tell.
After actively (won't crash if I don't touch it) using Photoshop for just a few minutes, my main screen will go dark, and my 2nd monitor freezes about 10 seconds thereafter. The problem started in roughly the past week or so seemingly out of nowhere. Perhaps an auto-update spelled my doom, I am not sure.
Here are some random bits of information which may prove useful in troubleshooting: - I am using Windows 11 with the latest build, and I'm on Photoshop 23.5.1 (latest version). - My main monitor is an ultrawide - I have uninstalled all but 3 plugins (Brandfetch, Glitch. Pexels) in my attempts to troubleshoot.
