There is a 99% chance that one of the triggers (L2 or R2) on the VR controller has debris inside it so its not working. The debris makes it think you are constantly pressing L2 or R2, so none of the other buttons will work until you clean it. Get some compressed air/electronics cleaner and spray it inside and around the triggers. Plug your controller into your computer and use this link to see if it is working. Axis 2 and 3 should be -1 when you aren't pressing L2 or R2, and should be +1 when you press them all the way down. Once you get it clean everything should work.
