Description
Our app has the following behavior after a fresh install when built with Qt 6.8.0:
- First launch: app crashes (stack trace below)
- Second and sometimes third launch: UI turns black about a second after launch, but app keeps running
- Subsequent launches: app works fine
The same app runs works with Qt 6.8.0 on Mac and with Qt 6.7.2 on Mac and Android.
