freezing in boss rooms

like 5/10 times the game freezes in a bossroom. Like i had it with trial of sekhemas and trial of chaos. nice when you have been fighting for 30-40 minutes to than freeze from nothing (no real big graphic card intense stuff). than the freeze stops when im already dead. Atleast make it so that when the game freezes, that is pauses the game. This is so annoying that im thinking of stopping. it wasted so much time now and i dont see any improvement or way me and many other players get anything in return for all these issues. Really hope this gets fixed fast

I'm having this same problem in the current league. Best case scenario I press escape and it eventually unfreezes, sometimes it's a full crash to desktop.
