Regression
I was unable to check
Operating system
Windows 11, Windows 10
Additional context
I have tried this on two different machines, one Windows 10 and one Windows 11. I am logged in as an administrator. Both machines give the same exact error and retrying just does the same thing. Neither machine has ever had MuseScore installed before via any method. This is the first time it has ever been attempted to be installed on either machine.
Both machines are running the latest Windows updates and do not have issues installing other apps from the Store, just MuseScore Studio.
