Make sure you’re running a legitimate version of the game through Steam, and that you have configured your OpenXR loader. For Quest 2 via Link that means you need to configure Oculus as your OpenXR loader, and for Virtual Dekstop you set SteamVR as your OpenXR loader.
I'm having the same issue, able to see the start screen saying "start new game", and can hear music, but clicking buttons does not do anything. Any fix?
Also using a Quest 2. Trying to play through Air Link, running a legit version through Steam, with Oculus set as the OpenXR loader.
