SteamVR is the default runtime. As far as I know, I don't think I have any addons.
Are you able to test with the Meta Quest Link app (Oculus Home) installed on your PC? No need to login/setup or anything, just the app installed.I have a feeling, even though you're not using a quest headset, that my game might have a dependency on it... (it was developed using their XR SDK)
