After updating Mac OS to 10.15 Catalina every attempt to save the MuseScore file (.mscx) basically freezes the application followed by eventual crash. This has rendered the application unusable.
Crash report is attached as a Word doc. I don't know if the Save File problem is included in the crash report but please attempt to recreate and fix the compatibility issue.
