Keep crashing in Shaper realm --> hunter wing

I am entering shaper's realm for the first time.
Completing the 4 wings before the Shaper appears i guess.

I've completed 3 of the 4 but when I go to the 4th wing I keep crashing.

Game has never had any GPU issues whatsoever but as soon as I enter this wing and do 1 attack, my game immediately crashes.

Anyone have any advice?
