File Recovery

Hi there,
I was working on a concert band piece for a few hours that I was really enjoying when it suddenly crashed. I hadn't saved it yet (which was dumb on my part) but for whatever reason, the "recover lost work" screen didn't pop up when reopening musescore. I've searched some forums to see if there is a way to recover my project but came up with no luck. Does anyone know if there is any backup file somewhere I can find?
Thanks!
