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".
