That means that vorpX couldn’t initialize the VR headset, which is a fairly severe issue. Most likely something is messed up on your system.
You *might* be able to deal with that by selecting a different headset type in the vorpX config app.
If e.g. you are using a Quest and currently have selected SteamVR/OpenXR, try native Meta Link instead. Most headsets should work with SteamVR, Meta headsets work best with Meta Horizon Link.

Sidenote in case you happen to use OpenXR while SteamVR is set as your system’s OpenXR runtime: Valve knowingly violates the OpenXR spec by not providing a 32 bit version of their OpenXR implementation. So Valve’s OpenXR cannot work with older 32 bit games.
