Problem details:
I tried to update to the stable version cause I can't even save my playes anymore on the fallback version but when I try to download the new stable version it downloads fine until I restart osu for the update to work it says that an error occurred on the last update attempt. I have no idea what to do its been stuck on the fallback version for almost 2 years now.

Video or screenshot showing the problem:
