Crashing at last Trial room

As the title says, I keep crashing at the last Trial room (poe2). This is my first time running it, but I get to the final room and every time I get to what appears to be a small boss arena, it crashes to the desktop. I've done the usual hard restart, and it's still occurring. I cannot progress at all in the story, I am completely stuck.

Same here.
I did finish some trials before (now I'm trying to get the third ascension points), but when reaching the first boss room the game crashes to desktop.
I have tried restarting the trial but it still didn't work.

Edit:
The game crashes when I get close to the boss, before any animation from him.

Same, I don't even see the boss, it stutters then crashes

I was able to make progress, but had to use a workaround. My friend had to kill the boss while I waited =P
