Whenever I start playing a video in Quicktime player it works for a few seconds and then the picture will freeze and the OS will become unresponsive (mouse still works), and then I need to reset my MBP.

I've also triggered a need to reset when I play a video in full screen in VLC.

I'm running the latest version of Sonoma. Monterey 12.7 did not have this problem.

Even not connected to the Studio Display Quicktime itself is also incredibly unresponsive in Monterey, cancelling out of fast-forward or rewind takes a couple of button clicks and there's always lag of a few seconds.

Any help would be massively appreciated.
