[Feedback Form] Crash on changing notes after transposition

"Ok - I was able to duplicate a crash. Here’s the scenario:
Import midi file.
Hide all instruments except violin.
Select all
Transpose to C
Attempt to move all notes up one step … crash

It is consistently repeatable."

I can reproduce on both 3.0.5 and master:

P.S.
In debug, the crash happens even earlier when you make instruments invisible one by one and you reach the last one:
mscore/instrwidget.cpp:511
Q_ASSERT(partiturList->currentItem() == item);
