I’m actually getting a similar error, using 4.8.2 compiled from Github.
One day I came into the office, and the Oculus Runtime just started crashing. It would have nothing but a black screen, and when I’d click that black screen… the runtime would crash and I’d get “57493-Public TCID:158609 is not responding”. I boiled this issue down to a problem with the latest Nvidia drivers, and had to roll back all the way to GeForce 347.88 before it would work correctly again.
Despite that, UE 4.8.0 refused to load anything VR related (neither Preview nor Standalone), continually crashing with this error:
I updated UE to 4.8.2, and it gives the same error.
Opening projects in previous versions of the engine seems to work. For example, a project I have in 4.7.6 works just fine.
