i tried oculus games, and they boot in vr without problems.
I tried verifying the files for steamVR and it found 2 files which it downloaded, still steamVR doesn't work.
Tried reverting to the non beta version and same result.
I tried pavlov in steamVR mode, booted in a window. I launched it in oculus mode and it started right up in VR.
Did some more testing and only games with an oculus mode work, and even those don't all work. Whatever I try, steam home doesn't open anymore.
Most games you launch through steam don't load or you get the message that your headset/controllers aren't found.
The games that DO work, usually are on the oculus store and have the oculus SDK.
Games that work are Pavlov, contractors, onward, saints and sinners.
Launching unity games from the desktop is a hit and miss now too, while before all worked.
Are you seriously locking link to the oculus store?
