I seem to be having the same issue.

The most noticeable place where this happens is when I try to exit my FC house. Exiting into The Goblet from our private Goblet manor, teleporting to The Goblet from inside our manor, or even teleporting elsewhere from inside a house reliably crashes my game while using DX11.

Northern Thanalan has also been very likely to crash for me on load.

Regardless, I switched back to DX9 and I am no longer experiencing these crashes.
