oops unfortunately this feature is not working.

I was watching a show on Peacock. When I tried to exit Peacock and go back to CBS I got oops unfortunately this feature is not working. I can change the tv channels. But the oops message stays on my screen. The only thing I can watch is ondemand. Do not tell me to check my cables and restart my box. I have done that 3 times. Nothing seems to be working.
