I added grace notes to a quarter note in one of my files, and suddenly Musescore crashed. When I tried opening the file again from the file explorer, Musescore would briefly open to a blank template then close again. When opening from the score launcher, the app would just close. I was able to figure out a method to repeat the crash on a test file, but that file was able to be opened again, so maybe the issue of not opening is related to the size of the file.

Steps to cause crash:
1. Open a new file with default format (I don't think format really matters) and place any note in any measure while in note input mode
2. Add any grace note to the note just placed and exit note input mode
3. With grace note selected, use the keyboard (press a, or b, or c, etc.) to replace the grace note with another note so that the new note is the same note length as the grace note
4. Undo the replacement
5. Move the grace note up or down an octave with the ctrl+arrow hotkey, and Musescore should close

Also, if anyone can figure out how I can access my file again (attached to post), I would be highly appreciative.

I was not able to reproduce the grace note issue, but I was able to determine the source of the issue opening the score. There was a hidden 7th instrument that seemed to have an invalid part definition. Removing that staff and part fixed the rest of the score.
