musescore 4.3.1 bug
I downloaded the newest version of musescore 4.3.1 and twice in the last two days it has simply died. It worked a while and then suddenly would no longer open on my Mac. I deleted it and redownloaded both times. I restarted my computer also. The first message was "Musescore failed to open" and the second was simply "can not open."

Try to reset Musescore from the command line:
