Sonoma freezes / crashes when playbacking videos in Quicktime

After I updated to Sonoma playbacking big video files in Quicktime freezes my M1 Macbook Pro. External screen is available, but laggy and all programs are freezed and not in use. Force Quitting programs in available but doesn't fix the freeze. Only way around is to hard boot.


Plz fix this asap.


PS. Thinking going back to Ventura if Sonoma is too buggy to use.

MacBook Pro (M1, 2020)

Please try the following: play a video via QT and do nothing else! Then move the mouse after a few minutes.

In my case, the videos start and play without any problems, but the computer freezes the moment the mouse is moved. Strange, but that's how it is.
