Necropolis of the firstborn 100% crash rate

i5-9600k
rtx3070ti
16gb ram
windows 10
previous and newest nvidia drivers both crashed (536.40)

100% crash rate in breathless landing area of necropolis of the firstborn.
After destroying 3 tumors and working my way to the 4th I crash 90% of the time.
Once made it a bit further then still crashed.
I’m at 7 crashes in a row. I tried lowest settings and adjusting dlss too. I tried toggling quality preset - windows size - closed all background including battle.net
I uninstalled the game and reinstalled. Still 100% crash.

Please help.
