Opening a MuseScore 2(.1.0) score with MuseScore 3(.6.2), saving and reopening causes a crash
Run MuseScore AppImage, attempt to open the attached score after the application starts. I was editing the score just yesterday; it was a MuseScore 2 score that I opened with MuseScore 3 and saved as a separate file. After selecting the score, MuseScore3 instantly crashes. Not sure what caused the score to get corrupted.

Fixed score attached.
I extracted the mscx from the mscz and removed all parts, then the score opened just fine. I've switched to page view and regenerated all parts, then saved. It still opens
OK, the fixed version of the file can be opened, saved, closed, and reopened safely. Thank you very much! Thankfully, I still had the MS2 file and didn't lose anything.
However, the error handling on file load should be fixed - no corrupted file should cause the application to spontaneously crash. Expected behavior should be that a dialog box opens and explains that the file became corrupted.
Additionally, I'm guessing this is repeatable with a MuseScore2 file that was opened with MuseScore3 - because when I tried to create a new (uncorrupted) MS3 score from the original MS2 score (and save it as a new file), it re-corrupted. Attached to this comment is the original MuseScore2 .mscz file (Northstar.mscz ) that was opened in MuseScore3. When I opened it, I selected all the checkboxes for using the new MS3 display features. I made some small changes to the file (there is some overlapping text towards the end that I removed) and saved it, and it reproduced the corruption. That should probably also be fixed.
We can only fix issues if we can reproduce them. This MuseScore 2 score might help in doing so.
I can confirm that simply saving that (2.1.0) score with 3.6.2 and opening it again causes a crash. Doesn't matter whether the new style or the old style is chosen.
