    Description

      MacOS 14.1

      Qt Creator 12.0.0-rc1 (11.0.84)

      Device: Samsung Galaxy S22 13.0 / Samsung Galaxy S9 9.0

      Qt Version:

      Qt 6.7.0 
2023-11-13
sha1: eadc7461ca268e97d9cec885cee9c5a59cc365f8

      Steps to reproduce:

      1. Create a new application or open an existing example, e.g. gallery quick controls example
      2. Run the app on an Android device.
      3. Rotate the device from portrait to landscape.

      Expected: The app rotates and works without any problems.

      Actual: The app crashes. 

      On Android 9 the app works until I rotate the screen. On Android 13 it crashed without rotating the device few seconds after launch. 

      Reproducibility:  100%
