There is a very rare bug where players can get stuck in the character creator, you can load a save slot if you saved before otherwise sadly this requires a full reset. So if you can't progress out of the character creator you will have to do a full reset in the main menu by pressing the following keys: LCtrl + LAlt + LShift + R, sorry you ended up being one of the rare instances where one gets stuck in it, either do the full reset above if you don't have any save slots, or just load from a save slot if you saved manually before.
