MuseScore crashes when joining measures & Exported MIDI file won't work in Reaper

[cunningar0807]

Issue type

Crash or freeze

Description with steps to reproduce

Recently yesterday I made tons of updates to one of my arrrangement pieces which was Chopin's Nocturne No. 20 in C-Sharp Minor. While i was trying to update the score, I included an updated Violin Cadenza. But as I attempted to combine the measures of the cadenza into one, the application crashed. Not only that, but there's even something wrong with the MIDI file import into Reaper. I actually did get rid of the mute articulation text from the other string parts before exporting the file into MIDI, which works, but when I import the MIDI file into Reaper, I get an error message. What's going on here?

I sure hope this'll get fixed before the next update of MuseScore Studio.
