Looks like EA got problems with FIFA 14 on Xbox One. EA things that two controllers connected may be causing the game to crash.
The EA Sports support page reads:
Using two separate controllers, both assigned to user profiles, and then using controller two to navigate the bootflow when FIFA 14 is loading can result in a crash. The FIFA dev team will be fixing this issue as soon as possible (shortly after launch) but, in the meantime and as a workaround: please only use controller one to navigate the bootflow of FIFA 14. You can turn on and use the controller two once in the main menu.
Users as well had reported a bootflow issue, which believed to be caused by leaving the console inactive until it sleeps.
If you suspend the console on the title screen in the Xbox One bootflow, you will not be able to access any online features when returning from an unsuspended state. As a workaround: don’t suspend the console when on the title screen. If you do, simply restart the console.
