There’s a good chance this is because you don’t have your your OpenXR loader set correctly. You need to go into the SteamVR / Oculus / WMR settings and set them as your OpenXR runtime. Note that if you want to use a Quest with Virtual Desktop, you need SteamVR as your OpenXR runtime. But if you want to use Quest with official Link or Air Link, you need Oculus as your OpenXR Runtime.
