Can You Convert Epub To Pdf On Mac

I'm totally desperated and finally want to receive help. I'm a Game Pass Ultimate member but I cannot login to Xbox with my account. So I'm not able to use EA Play which is part of my membership. If I try to login I only get a popup that I need to change my password. But if I do this it's the same problem. It's like an endless loop. I already contacted EA support and M$ regarding this issue as well. Nobody wanted to help me. In my EA account no Xbox account is connected so I can't unlink it. Onle Epic & Steam accounts are connected. There must be something "under the hood" I guess.
