Crash on save with specific project

I was successfully working on a project for a few days, but now it crashes on save 100% of the time with this project only (same thing with save as or auto-save). New projects are fine.

OS: macOS High Sierra (10.13), Arch.: x86_64, MuseScore version (64-bit): 3.0.5.21343, revision: 58dd23d

Troubleshooting attempted so far:
-Reverted to factory settings
-Disabled show start center
-Tried duplicating the project and renaming at the desktop level
-Tried moving the project to another directory

Crash log attached.

Thanks!
