Game crashing on lift to Alexandra Monastary

[Archer6616]

So I had beat the game a few times on Xbox, and until now had no issues, but after deciding I was just gonna be a little bit evil, and killed Seer Wiley before the quest where you confront him, I have figured out this breaks the quest and causes you to crash everytime you try to go up the lift to get to the monastery. Unsure if there’s a way to fix this beyond waiting for a patch so I can complete my evil run.
