Try starting a new game anyway. That's how you get to the chapter select screen.

You do not need to play the whole game again, you can start a "new game" in chapter 13 with the same character keeping level with the skills. If you "forgot" to do a quest in chapter 4 for example, you just need to start a new game in the chapter you want and do the quest. The Collectibles don't reset.
