Just turned my ps5 on only to see this

[u/CreationMage]

I’ve already unplugged and plugged in the hdmi cables at both ends. That didn’t fix it so I switched the tv and ps5 both off at the wall and that seemed to fix it, but I’m now afraid to turn it off in case it happens again

Faced the same issue, restart worked & didn't get it again.

Same. This is the fix for me.
