Can't play on PS5 -Downloaded free to try for the weekend

Game installed. On home screen and not able to "Press to Play". The only option I can select is the web icon towards bottom left and it opens the webpage where i sign in with an account but not sure what else to do. How do you even start playing this game?

The same thing happens to me.
You can press "O" and then "X" to try to enter the game, but in that case, it still doesn’t let me in — it says that the PlayStation Network servers are not working.
