SM6 video playback issue on Mac Studio M4 (black screen)

Summary

Hi everyone,
I have a Mac Studio M4 Max running macOS 15.7.3, and I’m using Unreal Engine 5.6.

If I play a video using Shader Model 5 (SM5), it works — but of course I lose all the advantages of SM6.
However, if I switch to SM6, the media player doesn’t work properly and only plays a black screen.

Does anyone know a solution to this?

Thanks in advance!
