Photoshop won't open existing documents nor create new documents
This problem existed in my CS4 that I formerly had installed. It's also happening in the current creative cloud Photoshop 22.1.1. I've uninstalled all of the CS4 utilities + Photoshop CS4 and reinstalled the current photoshop. The problem started about a month ago before I got the Creative Cloud license and rebooting will usually get photoshop working again.
The problem is that will silently not open a .psd or .png (or anything else I've tried) and does nothing when I try to create a new image. It might work correctly when I reboot but usually eventually stops working.
CS4 (once in a while) when I started the tool would give an error to the effect "unexpected end of file in clipboard". I haven't seen that error in 22.1.1.
I suspect the clipboard is involved and something that I do with the clipboard isn't compatible with Photoshop. Perhaps google slides? I'm not sure the steps to consistently make it fail. I use Edge on Windows 10. However, Gimp can create images from the clipboard when photoshop will not.
