HMDDevice isn't recognizing the Vive

As of 4.18, I am not able to run, view, or preview my projects in the Vive headset. Upon further inspection, I found that the Get HMDDevice Name node is returning “FGoogleVRHMD”. If I disable the Google VR plugin, then it returns “AppleARKit”. If I disable the ARKit plugin, then VR Preview becomes greyed out, and the node returns “None”.

My Vive is set up properly, as near as I can tell, and it works perfectly fine on all projects in previous versions. I even tried making a blank new project using the VR Template, but found the same results. I also tried restarting the computer, deleting the Saved and Intermediate folders, and running all applicable programs (the editor, SteamVR, etc) as an Administrator, to no avail.

Does anyone else have any ideas that I can try, or know what’s going on here?

Can anyone from Epic confirm if this will be among the fixes in P3 this week?

Confirmed still occurring in 4.18p3. Marking as solved, and re-posting to the Bug Reports section.
