Description
1. Open attached score.
2. Double-click note (entering 'edit mode').
3. Click on the score (exiting 'edit mode').
4. 'Play' immediately and repeatedly.
Result: Crash.
Discussion: Sometimes you don't have to click repeatedly, it'll just crash if you stop playback.

Persistence maybe required for this somewhat difficult-to-reproduce crash. I managed in 5511, but am now struggling.
It could be the answer as to why crashes occur when stopping playback. I wonder if it's something to do with the soundfont, and if it's connected to this: #13528: Closing score during load of navigator pages causes crash
I attach a crash log from a previous version (5483), when I managed to reproduce (using another score).
An alternative way to reproduce (perhaps the title could be changed once we know what's wrong):
1. Open score.
2. Drag note somewhere.
3. Play repeatedly.
Result: Crash.
Discussion: See crash log.

According to this last log, it's a crash in the synth
1 net.sourceforge.mscore 0x0103692b FluidS::Fluid::process(unsigned int, float*, float*, float) + 43
2 net.sourceforge.mscore 0x00ff9c21 MasterSynth::process(unsigned int, float*, float*) + 145
3 net.sourceforge.mscore 0x001ac0ce Seq::process(unsigned int, float*, float*) + 1166
4 net.sourceforge.mscore 0x00343270 paCallback(void const*, void*, unsigned long, PaStreamCallbackTimeInfo const*, unsigned long, void*) + 64
5 libportaudio.2.dylib 0x05434f5b Pa_GetSampleSize + 6843
6 libportaudio.2.dylib 0x054359e9 Pa_GetSampleSize + 9545
7 libportaudio.2.dylib 0x05439e7c PaMacCore_Initialize + 9852
This is apparently another way to reproduce with the same result (can't remember exactly, but these maybe the steps):
1. Open score.
2. 'Mixer'
3. 'Play'.
4. Change sound.
5. 'Stop'.
Result: Crash.
Discussion (see crash log).

#2 is actually another bug: #16016: Note shouldn't be selectable or editable while playing
This may have been fixed (https://github.com/musescore/MuseScore/commit/25bfd0d)?
I believe it's fixed.
