Oculus VR 4.3 UE4.6 Crashes on launch

Been trying to get Oculus DK2 to run however whenever the Oculus is turned on, the engine crashes and never starts up.

This is what the log spits out. It starts up if I have extended desktop but it doesn’t detect the rift.

It also crashes with 4.5 and 4.4, so I must have not set something up right.

Update: I can get it to work with Extended Desktop Mode only. Maybe it has to do with Nvidia?
