Lost Files

Hello

So I've had MuseScore version 3 2 for a while and I'm having saving issues. I was working on multiple scores at once, the scores were opened via "open recent files". I saved the files by clicking save. (I've poked around and found I likely should've saved it to my computer under a new name.. But that doesn't explain the real issue.) The files are nonexistent on my device now. I had to save them all and close MuseScore to add my headphones to my device. I opened it back up and the even the starter files saved on my device prior to their edits were gone, no names, no keywords, nothing. A bunch of random "scwllssksl" titled copies of files, but not for all of my opened files and they weren't up to date either. Did the server crash? Should I just restart my computer?? I emptied my recent files too so even the faulty copies are missing, but I know I had at least some of these files saved to my device... Any pointers? I would show you the scores but I don't have any.
