Musescore file corruption. Too many notes?
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.
