A solution was given to me via Discord.
For anyone else encountering this same issue, you have to go to C:\ProgramData\Animation Labs\vorpX
Open the vorpX.ini file, and change “sDeviceIniName=Oculus” to “sDeviceIniName=SteamVR” (or whichever VR platform you’d like to use).
I’m assuming my PC was preventing this change from occurring after switching the General-Device Selection settings on the program, so I had to manually change it myself.
