I am getting this same issue on Xbox. It appears previously EA generated their own emails to use for EA accounts when you played on xbox I tried to link my EA account and get this message (attached image). Look at that email 😂 no account I have ever owned now my Xbox account is permanently locked out of any EA games.
I have the exact same issue on Xbox as well. Can’t access my old account. When I try to link my new account to my Xbox gamer tag, it says an account is already linked. When I try to search by email, it says no account exists under this email. Wtf
