MuseScore won't launch on Flatpak
- Open MuseScore
- MuseScore doesn't launch
Terminal output shows :
unknown:unknown: Qt: Session management error: None of the authentication protocols specified are supported
I think it's caused by the Flatpak using Qt "5.15-21.08" branch, because it runs fine when it was "5.15". I'm not the maintainer, so as a workaround I just downgraded my installation. What version of Qt was MuseScore supposed to run on?
