I don't really see CSP (Clip Studio Paint) in the painting software list. Maybe I missed it. You could add that one. It's pretty cool.
I wanna recommend Photopea https://www.photopea.com/ for psd recovery though. If a file gets corrupted (usually if your PC shuts down while saving a file) it's GG. Or at least I thought so, having been unable to recover my file until I found this tool. You might lose some layers but generally the .psd will be intact.
