A couple of people have reported this on a PC or Mac.
I don't know if there is anything on this link thread below helps.
Here's another thread, where both threads seem to be Windows PC, so not sure if it is also Mac relevant because I have never owned a Mac.
Hopefully it will give you some pin pointers.
There used to be a lot of reports on the Sony Community of people saying the only app they could get on was Netflix; and this was traced to Sony incorrectly handling the clock.
it turned out that this could be fixed by setting the TV to use Network Time; and Netflix was the only streaming app that didn’t care what your clock was set to.
This sounds like exactly the same issue, albeit with a different reason for the clock being wrong.
But all these apps just refused to work, and wouldn’t say anything useful, like ‘Our clocks don't agree’ 😢
