edit: I think I found the source of the problem all folders on all drives are read only this is really annoying
Are you still sure there are any files at all? What does this disk do on another computer? Or what do you see when you start your computer from a Linux live drive/USB, for example? I ask it because I have seen similar situation, all files were on drive, but were not movable and at all usable if pc was run Windows, but everything was possible save to other place if to use Linux and after that was needed fix and reformat drive and everything worked again and this drive works till now.
I have dual boot with windows 7 and windows 10 on the same laptop and they are fine, never faced such issue, I have this problem only on windows 11 newly installed last week, i dunno what exactly i did caused this, maybe i should just reinstall it
