New Oculus Rift S, arrived today, the tutorial worked after the setup.
After a while I downloaded more games and put the oculus aside.
After few hours when I tried to play again nothing worked, I couldn't see anything, the sound did worked.
Tried reinstalling the Oculus app, unplug and replug the cables, updated windows and graphic drivers.
It's really sucks for first experience like this on the first day.

Have you tried disabling your USB port power management options?
You want that turned off.
I see you said you tried unplugging/re-plugging, but have you used different ports?
And fully rebooted from cold, not just a restart?
