When I try to enable tVR it just says an error: object reference not set to an instance of and object.
and when i restart the program and steam vr it puts no in the tVR option
Not sure if this is correct way (as the way shown in the tutorial doesn’t work for me either) but I forced the tVR to work on my pc by starting the SteamVR in safemode and after few moments a pop up showed up with asking me to restart SteamVR, before clicking it I set up the tVR to ON and than press on the pop up.
After a the restart SteamVR turns and right after that the driver4vr also turn on,from now everything should work just fine.
