Rift S will not work in Oculus mode if you use Steam. You must use Steam VR. Oculus mode is only for the original Oculus CV1. Since you tried using Steam VR and it didn't work, you have other options. You can look in in your Oculus Library and will likely find that Automobilista 2 is listed. After selecting play, you will be taken to Steam but you are entering though Oculus, which may prevent the crash. Another way is to use the nvidia doorway in the GeForce software. This is spotty as nvidia doesn't alway pick up all your sims. Hope this helps.
