XR Settings>Virtual Reality Supported not working for my Oculus Rift

I had a project with VRTK and Oculus SDK working fine a few days ago. Tried to run it last night in editor and i could see my headset and touch controller movements tracking in the game window, however in my headset I get stuck on the Unity loading window and it never works. I've tried updating every possible client and driver, fiddling with permissions and even turning it off and on again. (I know, serious stuff) I eventually downloaded a fresh version of Unity (2018.2.18f1) and started from scratch by very simply enabling the VR support in player settings but get the same issue. I've spent a total of 8 hours since last night on this issue and have come up with nothing except for a series of mental breakdowns.

Has anyone experienced this problem or know why this isn't connecting to unity?
