Error When Saving to the Cloud

When saving a recent project, a message was displayed saying how Musescore wasn't able to save the file to the cloud due to an authorization requirement. To attempt to fix the issue, I checked to make sure I was signed into my Musescore account by opening another window of it, in which I confirmed I was signed in. After attempting to save the file more to no avail, I closed the window of the project (no window opened giving an option to save like a usual unsaved project, it closed immediately). When trying to reopen the file, Musescore gave another error message, saying how the file I tried to open was invalid, denying me access to my song. This is where I am now, not being able to reopen the chosen song. Does anyone know why this happened or how to fix this issue? Thanks
