Saving error

I use MuseScore 4, and it is not saving all my scores. It comes up with an error that says, Your score could not be saved, Underneath that, it says, An unknown error has occurred while saving this file. I use a Windows 11 Dell laptop. I have plenty of space left on my computer and OneDrive, so that is not the problem. What I noticed is that it has been doing this ever since I updated to MuseScore 4. I am working on a project for my songwriting class final, and I need this question/problem figured out quickly so I can start recording and not have my laptop sound like a helicopter taking off since I can't close the programs.
