Problem linking Xbox account to EA Play

Good people.

I'm having a problem linking my Microsoft Xbox account to my EA Play.

As you can see in the images, when I try to link, through the panel, I am redirected to another tab, saying that it was not possible to link, because my Xbox Account is linked to another EA account, this one from 36******@ disabled.ea.com

Since I don't know what this account is, and I didn't find anything here on the forum that would help me.

And I don't have access to this account to unlink
