Musescore file corruption. Too many notes?

• Sep 24, 2019 - 03:37

So, I've been developing this approximately 10 minute arrangement of some songs from Deltarune. It started in Musescore 2, then made the just from Musescore 3 just fine. However, I've been making iterative changes for months, coming back and tweaking things, adding things, making it better and better. However, a few weeks ago I saved the file, and upon trying to open it again, Musescore 3 would instantly crash. Everytime, no matter what. Luckily, I keep all my music in a Google Drive folder, so I had an earlier version that wasn't corrupted (yet). Tonight I was just making changes again, and after adding a Gong part, and adding a few notes to the bass drum part, Musescore just crashed, and the file will refuse to open. Even in MuseScoreNightly-2019-09-23. Can anyone please help? I've attached the file. I'd hate to lose the ability to continue editing this. I'm legitimately crushed that this is a bug that exists. I hope no one else has experienced this.

I can confirm the crash, happens too with the lates development build.

The score uses MDL and mixes sounds from MDL for MuseScore 2 with those from MuseScore 3, MDL 1.1 vs. 1.3. This may or may not work, but probably is unrelated to the crash, which seems to be about elements not being linked between score and parts.
There are indications that this score started its live as a MuseScore 2 score, which then got imported into MuseScore 3. It got last saved with 3.2.3.

I've been able to manually remove all (linked) parts from it, so the (master) score now loads again, and you should be able to generate the parts afresh.
