Starting last night, after I open the client (ps4), it displays the initial splash screen before it loads the login screen, then hangs indefinitely on a blank black screen and I can't get to the login screen. I can still access the playstation menu from here, it's not frozen, and I can play other games and access the internet. I haven't changed any settings recently. I've reset the ps4, the router, the modem, deleted the client and reinstalled it fresh, and I'm now out of ideas.
