S90F48 potential bugs with PS5?

Bought this tv the other week, picture is 👌🏻

I use it mainly with my PS5, oddly it has shown weird behaviour.

Using game mode, 99% of the time game mode on auto boots up, then doesnt.

Image settings just change out of no where and then im face with initial ps5 setup of having to set hdr...

I cant be the only one? Any fix?
