    Description

      Application crashes with official Qt Camera Example on macOS 13 Ventura.

      Way to reproduce:
      Build and run the official Qt Camera Example, and click device item (in menu bar), your iPhone will send notification and application crashes.

      Please see the terminal warning.

      Issue is plausibly in [AVCaptureDALDevice setTorchMode:] which will cause the application to crash.

      This is a macOS 13.0 specific problem which uses the Continuity Camera which is a new function.

      Terminal output:
      2022-10-25 12:34:35.779 camera[6146:74167] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[AVCaptureDevice_Tundra setFlashMode:] Unsupported flashMode - use -isFlashModeSupported: to discover valid flash modes'
