Crash ID doesn't exist, did you paste the wrong hash bill? Also P3 seems low for a crash bug if you found it in the wild.

wasn't "in the wild" if I remember correctly, but did hit locally once when testing other things.

I have the oculus equivalent fix uploaded, and can start on this soon.  boosting priority.

Fix up OpenVR threading and session lifetimes

This is similar to a change made for Oculus devices.  OpenVR is
initialized when we have a magic window session, and can only be used on
the UI thread, or it can be initialized on the render-loop thread, and
we will only use it on that thread.

Gamepad data is now updated per-frame by the render loop, with data
passed over to the gamepad fetcher and read in its polling thread.
