Game locks up when accessing system settings

[Eipher]

Okay a little more digging and I think it's due to a bug related to the Immerse spatial audio plugin.

I tried all this without my headphones plugged in. Switching to DX9 I could access the menu again. After noticing spatial audio was a DX 11 exclusive feature, I tried starting the client multiple times with/without headphones plugged in using DX 11, and every time without fail if I had no audio connected to my PC the game locks up, either at startup or when I try to access the system config menu. Conversely, the client runs fine with audio plugged in.
