Game crashes with engine error every time when climbing a ladder in an elevator shaft

Hello it’s me again.

My game crashes every time I climb that long ladder in the elevator shaft a bit after i swam in the reactor’s coolant.
I’m adding a screenshot to show where exactly my game crashes. I tried going through it quite a few times but the game will always crash and give me an error message

Engine Error Too many verts for a dynamic vertex buffer (38984 > 32768) Tell a programmer to up VERTEX_BUFFER_SIZE

I’m also adding the minidump file for a couple of those crashes.
Hope it helps!
