MuseScore 4.0.0 (release) sporadically crashes when saving online & locally
S2 - Critical
System: Windows 10, v10.0 b19045
PC: Alienware 17R4
Difficult to reproduce all cases, but constantly crashes on playback and idle, including Home screen.
Following cases are reproducible:
1.1) Created score (see attached)
1.2) Save online
1.3) Dialog for saving online pops up - clicked Save
1.4) Dialog closes & crashes
2.1) Created score (see attached)
2.2) Saved online
2.3) Received "Cannot save online" popup
2.4) Clicked OK
2.5) MS4 freezes & crashes
Also seems to log me out of MS4 (see screenshot) on next launch & attempting to "Save a copy"
Saving locally (ie clicking "Save to local computer" on Save dialog popup) also crashes MS4
If saved online, bug is reproduced - a fresh score with no URL attached (ie not saved online prior) can be saved normally; however once URL attached, saving locally & online crashes per description.
