SteamVR with oculus quest 2 not working consistently

So when I add a player prefab (steamvr folder has a player prefab) into unity, I was able to hit play and see the world thru my headsets. But next time I open up this project, I get these errors.

I didn’t change a thing and yet it worked last time. I have everything configured (at least I hope so). Yet I still get these errors. I would appreciate anyone’s effort to help.

It would be worth checking out: SteamVR Unity Plugin | SteamVR Unity Plugin for SteamVR issues.
