Corrupted Score + Online Download Error

I recently updated one of my old original compositions in MuseScore 4. After I saved the file and made some changes, I tried re-opening the file, but then I get a message saying it was corrupted. It still opened pretty good though.

But things get worse once I try updating the score to my account. After I've done that, I get a download error that occurred.

I have a link to the score right here: https://musescore.com/user/5012316/scores/3666511?share=copy_link
And if anyone else is having the same issue, then there must be a huge problem.

I even attached the .mscz file. Unfortunately, I don't have an uncorrupted version at all, but if it still works in MS4 for you guys, then that's good.

Cansomeone please help me with this huge issue?
