Exact situation here.
The game launches fine for me, but my son received this error and cannot play Battlefield 6.
I did note I needed to select a tick box accepting marketing emails from EA when launching the game for this first time on his console when logged in as myself. This tick box isn't appearing for my son so I guess this has something to do with the way EA children's accounts work which is the unlimited cause of this issue.
I hope EA fix soon as he is devastated not being able to play alongside me.
