Musescore 3 Not Responding

Hello,

I've been trying to open Musescore to write something for someone in my drumline and it doesn't seem to want to open. Whenever I go to open it, it asks if I want to restore session. I hit no, and then it will try to continue but then say "Not Responding" and won't do anything else.

I've tried deleting it and reinstalling it, opening a specific score, and it still won't open. Someone help please. Thank you!
