QMediaPlayer crashes on Mac OS X

Strangest thing. I've got a simple media player to play instruction video's. When an instruction video is selected it creates a Separate Window with a media player and plays the video. Normally over an internet connection.

On Windows, using Qt 6.4.0, no problems, On Mac OS X, using Qt 6.4.3, the player crashes. 

I've created a test application. I see following behavior:

• When I create the media player widget with the MainWindow, no problems. 
• When I create the media player widget manually and add it to the MainWindow: crash. I narrowed the crash down, e.g. instead of playing right away, I've prevented it from playing right away. Then, when I click te 'play' button, it crashes when it starts playing. 

Using Qt 6.5.0 on Mac OS X, the player does not crash anymore, but is also not able to play video's directly from the internet anymore.

Some logging (6.4.3):
