This document does not appear to be a valid psd file

I made this drawing and a couple days later I couldn’t access the file. It says Format Not supported. The document does not appear to be a valid psd file. This is so crazy because I had the same problem for my other drawing a while back but there was a solution where you create a duplicate and it works fine again but now that method isn’t even working. I have downloaded and logged in on pc and the file still won’t open meaning it’s probably not a device problem. If anyone has found a solution please help.
