Same thing over here - but after this happened on and off with FIFA 23 on PS5 for me i was at least smart enough not to buy the ultimate edition. You're right though - customer service is not anywhere near where it should be - they just close out the tickets without even responding to me.
I've tried clearing cache, rebuilding database, and resetting my ps5 all to no avail.
Nice little bonus for the hour download time every time i try the above process hoping that this time the result will be different.
From the research I've been forced to do on my own (because EA is literally NO HELP) has me thinking this it's beyond software and unfixable short of sending my console in to be "repaired" (even though there's seemingly nothing wrong with it) for the low low price of $250.
Would love someone to prove me wrong - i just miss the days where you popped a game in your console and it worked...
