[XBOX ONE] Dragon Age: Inquisition won't launch, crash to dashboard

Go into your Xbox One settings;

Network Settings->

    Advanced Settings->

        Alternative Mac Address->

           Clear

This will hard-reset your xbox one, and you should be able to get to the Dragon Age main menu after that, and just continue your game.

This also makes me think it's a server side problem at EA, and not a client side problem in our Xbox Ones, and games.
