No problem for me. It’s usually a hdmi hdcp issue and very likely down to the TV (Make and Model of TV would help). It’s worth checking if a software update for the TV is available.
Next time it happens try the following.
Select a different input on the TV and back to the HDR one.
In settings on the box change the output resolution and then back to the one you are using.
Either should force a new hdcp handshake.
Rather than a reset unplugging the power supply for 10 minutes or so may also resolve the problem.
