I can't save anything on MuseScore 4

Hello, I found an issue that probably other people found, and I seriously need help with this.

Whenever I try to save a score to the cloud, it says I don't have authorization. And when I try to save it to my files, it simply won't download (even if it shows that it is downloading). I tried to log in and out of my account, and tried to save It again, but it just wouldn't work. I even reinstalled MuseScore 4, but the same thing keeps happening again. I don't know what to do or what's going on with MuseScore 4, because me, my friends, and probably many other people have the same issue. To be honest, I was excited to try MuseScore (since I never tried it before), but now, I'm just thinking of not trying it ever again, unless this bug gets fixed.

Please fix this bug, it's annoying, especially for those who make entire songs just so they lose all their progress.
