Consistant crash when transitioning to Scourge

Currently played up to near the end of act 5 and been getting consistent crashes to desktop when transitioning to the scourge version of instances. Been trying it regularly in all maps since Tidal Island and it's mostly as soon as I start the event or a couple of seconds after. I have managed to get some runs in and I've tried with DX11 and Vulcan rendering to see if there's any difference with stability and it's pretty much the same.

Drivers are up to date.
