Okay, I have my PS4 back from my brother's house. So I can confirm myself that deleting the whole game and reinstalling temporarily resolves this issue; and logging off and shutting down completely, unplugging, does not bring it back (as of yet), because my ps4 had to be relocated for the update. Whether or not I will actually be able to play, remains to be seen, but at least my game WORKS for the time being. That's such a relief. All these people complaining about lag and congestion are taking for granted that at least they can try to play... :[

I think I nearly cried when that 'play' button popped up instead of a 22gb patch. Even so, I'm petrified to actually play, it's summer in a rural area for me, and that means random power outages...
