Alright, got it working. Had to uninstall old runtimes. Install the new oculus runtime for the consumer version. Setup Your Oculus: Quest, Quest 2, Link, Rift S & Rift | Oculus then open the new oculus control app. (just load the oculus.) then go to settings>genera and turn on the “unknown sources” to allow it to run in UE4 4.11.1 VR preview should be back.
