VR is not enabled for this application and NullReferenceExceptions

[feroxxy]

These errors pop up in the example scenes. I've tried it in both clean and active projects in Unity 5.5.4 , 5.5.5 , 5.6x and 2017.3. Sometimes it works for a while and the moment I boot up the project later its gone to hell. What's happening?
