Save not working

I have a score that I've been working on, but suddenly it crashed. Now every time I open it and try to save it, musescore crashes. Even if I Save As, Save a Copy, etc. it crashes. It also leaves a "title.mscz_saving" file in my scores folder. I've tried duplicating the file in finder and when I try to save that it crashes too. I'm not sure what to do here.
