Musescore Won't Stop Crashing

I was working on a piece for low brass ensemble when musescore 3 suddenly crashed. I tried reopening the app, only to result in it crashing immediately. I tried to restart my computer, but that didn't help. I looked for answers on this forum to check for possible solutions and tried a factory reset. This didn't work either, and the app would immediately crash. I also tried opening the score from my files, not the start center, where the score briefly loaded, and then crashed. I don't know if something got corrupted, but I can't get musescore to work. I'll attach the file.
