Can't open my musescore file after my laptop crashed.

I was working on my musescore file for school before my laptop suddenly crashed out of nowhere and now my musescore file is 'corrupted' and won't open. What's even more annoying is that I literally saved before my laptop crashed so musescore just straight-up overwrote my file with a corruption for no reason. I've tried everything from updating my musescore to turning it into a zip file to unzip it (winrar didn't recognise it as a proper zip file). Do I have to restart or is there a way I can recover my schoolwork?
