PS4 crash on loading

Hi guys. New to this forum malarkey. I bought and downloaded this yesterday. Played fine for around 2hrs. Tried to have a go this afternoon and I get the screen for a moment, then blackness. Tried restarting the system. Turn off and on. Anybody else got this issue?

Unfortunately you might have delete game but idk it risky you would all proggress so youre choice
