MuseScore crashes when deleting horizontal frame from beginning of orchestral score

Hi all,

You can see in the attached video the problem. I can't seem to delete the frame because each time I try to do that MuseScore crashes. I'm working on macOS BigSur 11.6 Mid-2015 MacBookPro (Intel i7).

Seems like a pretty serious usability issue, I hope this helps!

PS it also crashes when deleting a whole part, probably it's about handling larger projects changes.
