Crash on startup with AddressSanitizer on
After the introduction of the new palettes, MuseScore crashes at startup (i.e. a memory violation was found) when AddressSanitizer is enabled in the build.
This could be related to the random crashes that were reported about MuseScore 3.3 Beta.
Attached the stack trace of AddressSanitizer.
Unfortunately, I have too little experience with the qml infrastructure to be able to fully understand what is happening.
