I have the typical problem with my Rift S of a black screen but with audio. The headset shows up as connected in the app. The headset was working 1 week ago. Most strangely, if I make a new windows account, it works perfectly. So far I have tried:
unplugging and replugging
restarting the oculus service
reinstalling oculus software
deleting appdata and reinstalling
updating nvidia drivers
deleting all razer software
replugging the cable on the headset (though, like I said, It works fine on other accounts.
downloading the public beta oculus software I'm just not sure what to try from here.
