ACT 9 - Multiple crash to desktop - Can't continue progress - Storm Blade

The second the mummies start spawning the game hangs once for a half second comes back then crashes to desktop.

I've restarted the instance, I've tried dx11/12/vulkan, i've tried not using my merc. Knocked all graphical settings to low.

Eventually, i just tried to skip this quest, but the same thing happens at the quarry while starting the Kira fight. tried all the same.

I'm on try 19, I cant do it anymore. I Cant complete this act.

I'm on latest drivers, I use the stand alone launcher.

I've never had anything like this happen in this game.
