Does your ActiveRuntime look like this?
Regedit path: “Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenXR\1”
The entry for your ActiveRuntime should look like this:
“C:Program Files\Oculus\Support\oculus-runtime\oculus_open_64.json”
If it isn’t it might be on SteamVR. You need to change the entry (assuming you’re not running the Steam version of FS 2020) or won’t find your Quest 2.
Edit:
Nevermind. It appears you know about the registry edit.
