FC24 constantly stuck in reset password loop

Bought FC 24 today and went to play it, as soon as the game loaded in it spat me to a page with a QR code so i followed the instructions to reset my password, Password was reset no problem but I cannot log in to FC24 everytime I start it up it spits me back onto the page with the QR code. If i try to link my ea to xbox it says Your accounts can’t be linked because your Xbox account ********** already linked to your EA Account for *******@disabled.ea.com. An EA Account can only be linked to one Xbox account in its lifetime.

can anyone help please
