screen mirroring appletv+ causes black screen

I open Apple TV plus on my new iMac and start watching a movie. But when I screen mirror to my TV in the lounge the movie on the iMac goes black but with audio. The black screen mirrors to the TV as a black screen including audio on the TV. If I open a YouTube video on the iMac, it screen mirrors to the TV as expected. The error seems to be linked to trying to screen mirror Apple TV plus. I have set Mirror Built-in Retina Display.

iMac 24″, macOS 13.5

Thanks, I am clicking the screen mirroring button on the iMac....not sure if that is AirPlay or not. And when I do click on Screen Mirroring, the tv+ window goes black. Strangely If I start watching the Apple TV+ movie from my iPad I can screen mirror to the TV as expected. it seems it is only Apple TV+ that is giving me this problem. My iMac seems to screen mirror any other application. Regards Des
