Game is frozen and I'm not sure what to do

I got to the part in Utira town where you choose to battle Damian or Nora by the entrance to the library. I beat Nora and the game froze as Damian and Nora walked into the library. The only buttons I can press that work are to quick-save and toggle autorun. I can’t walk or open the menu. If anyone knows how to fix this please let me know.
