MuseScorce does not startup on my computer, consistently crashing with a segmentation fault. I am running i686 Arch Linux. When running with no debug option: the splash screen shows, then the program crashes. With debug option: the splash screen shows, the start centre window opens but remains blank - the program hangs, then crashes.

The program used to work correctly.

I tried deleting the settings in the home directory and in the .local folder but the issue persists. I also tried running using the -F option, as well as the debug option. I tried the 2.0.3 AppImage and the nightly image. These versions crash too.

Stable debug output:

Comments

If this occurs on multiple versions of MuseScore, and did not happen before under the same circumstances, it sounds like a conflict within the computer rather than within the program.

Can you identify the date when the fault started?

What changes did you make to the computer (or did it make to itself, via 'automatic update') on or just before that date?

Can you run a 'system restore' on that OS? I am not familiar with Linux.
