      MacOS 15.6.1

      Qt Creator 18.0.0

      Qt 6.10.0 RC

       

      Device: Samsung Galaxy S22 14.0

      Steps to reproduce:

      1. Run the media player example (I used widgets player, because QML is often crashing on Android, but both crash with this file) on the device.
      2. Open the attached audio sample file.
      3. Tap on play button.

      Expected: The audio file is played.

      Actual: The app crashes after tapping play button. 

      NOTE: No crash on desktop.
