I've tried reverting the version change but that crashes in the same way:
https://github.com/flathub/com.github.Rosalie241.RMG/pull/99
I've also tried downgrading the runtime version to 6.8 but that *also* has the
same issue:
https://github.com/flathub/com.github.Rosalie241.RMG/pull/100
STEPS TO REPRODUCE
1. Try to compile a Qt app
2. it fails to launch
