Saving a non-existent file

Open musescore. Exit out opening page. Save file. Error tag pops up “this file does not exist”.

I can’t save the file or anything. This isn’t happening with just one file. It happens with any new fix that didn’t exist before. It doesn’t matter if I change the name or downgrade or reinstall. It still pops up.

You’re suppose to get this message if you try to open something that doesn’t exist. I don’t know why it pops up when I try to save something. It’s very very infuriating. It didn’t happen until yesterday.

I called windows to see if they knew anything thinking it might be something with my computer but they didn’t seem to know how to fix it either so I’m hoping it can fix it here very soon.

Please help.
