Just got this same error when booting the game. Can't even get to the title screen. Anyone else having this issue?
Tried resetting the game and restarting PS5. Tried to get in on my Singapore main acc and UK alt acc. Nothing works. PS chat and PS Store works fine. On wired connection, 769mbps down and 140mbps up.
Say whatever you want about TDU:SC; at least that lets players see the title screen. I love modern games so much.
