When I open the score below, both Musescore 3.4 and the nightly builds crash. What's wrong? I can open it in Musescore 2. Is it a compatibility problem?
The score is here:

Load the score into MuseScore 2, insert a system break after measure 520, and save the file. You will then be able to load the score into MuseScore 3.4, but it does take much longer than loading into MuseScore 2, and it will warn you that the file is corrupt. But you can ignore the warning and edit the score anyway. The glissando in measure 521 was causing a problem during layout since its end element did not yet have a system, but forcing it to not span multiple systems makes the problem go away.

Not a blocker (as you can use MuseScore 2) and also with a Workaround (see above)
