Particular .mscz file crashes MuseScore 3.0.5 before it can open
Upon double-clicking a particular .mscz file, Musescore begins to open (showing the logo and version number) but then abruptly crashes. In subsequent attempts to open the file, a pop-up box offers to reopen windows from the last session. Whether accepted or declined the program crashes. There is also a second pop-up box offering to restore the last session, and nothing happens when an option on that box is selected. (I've attached a screenshot for reference.)
If Musescore is opened first, and then the .mscz file is opened from Musescore, the program crashes.
The program first crashed while I was working on the score, so this version of the piece updated and I didn't have a chance to manually make any backups elsewhere.
The file is attached below as "Elle".

See https://musescore.org/en/node/52116 for how to recover backup files MuseScore created for you automatically.
Latest development build crashes on it too.

Looks like a tremolo between 2 notes where the 2nd note doesn't exist?
After some code mods I can load the score and see this:
![Elle.png]( "Elle.png")
I don't understand how a whole note can possible fit into a 3/4 measure, or how a tremolo between 2 half notes can?
Attached a 'fixed' score with those tremolos removed, it loads in 3.0.5 again
And here's one with the notes still in place and 'fitting' durations, but without tremolos
For the code change needed to read that score without crashing see https://github.com/musescore/MuseScore/pull/4973
Do you have any idea how you got into that situation, any steps to reproduce this?
There's another PR that, amongst other things, partly is doing the same or very similar changes, https://github.com/musescore/MuseScore/pull/4730, to fix #278999: Need option to completely disable Auto Placement.
That needs to go in first it seems and maybe fixes the problem already, to be seen if and when that one got merged
OK, it seems to be just one of the tremolos to be the culprit, the very first in the score, in measure 140.
Attached the score with just that one removed. No visible difference between the 2 in the 'fixed' MuseScore version (which avoids the layout in this particular case, so this is probably to be expected). The Score Comparison Tool though does mention "Measure 140: removed element Tremolo"
Now waiting for https://github.com/musescore/MuseScore/pull/4730 to get merged, I closed https://github.com/musescore/MuseScore/pull/4973, as the former now contains everything needed to fix this issue from the latter.
Fixed in branch master, commit 6b7f33ec64
fix #278999, fix #288474: autoplace customization

Thank you so much for the prompt help! Sorry I've not been able to respond sooner. The modified files are working for me.
Looking back at the files that you modified I think I know what happened. I moved those tremolos (in 4/4 time) to late in the score because I wasn't sure if/when I wanted to use that section. I forgot that this bit was there and changed time signatures to 3/4 earlier in the score. I guess the 4/4 notation couldn't fit itself into 3/4.
OK, with that I can reproduce the crash in 3.0.5 and 3.1 Beta, no longer in latest development version, although something doesn't look right there. Now reported in #288576: Strange results when changing 4/4 measues with halfnotes tremolos between notes to 3/4
