I have a similar brand new Mac Studio computer. I am not running any mods. My game freezes on many but not all character dialog cut scenes. It ALWAYS freezes on the Goblin Fight fairly early in the game. I have found no way around this.
I have done everything suggested by Larian without success. (At least 20 hours of reducing graphic settings and disabling thins and that basically everything they recommend and more.)
I filed a report with all of the detail they request.
They thanked me for my report and said it is a known issue they may be able to fix in the next hot fix.
The game is really awesome so I will wait.
Good luck all
