Instant crash with slurs on mac

I've had this problem in the beta, and now also in the official release - whenever I try to add slurs to my score that connect more than 2 notes, Musescore 3 instantly crashes. It doesn't happen to every score, so I'm starting to think it's just this one, or that it has to do with the size or something... Anyone any ideas?
