I saw this last night but it was affecting the person in my group rather than me, so I suspect it is a local issue rather than a game issue. I went through the cut scene without him in the end which let us finish.
Maybe running a repair on the game files or re-installing the game might help? Could even be a driver issue if the last patch contained video updates or any kind.
That was the first thing I did. Didn't make a difference. I also just ran it just now and both of us crashed. Now I'm stuck in Esseles and forced to exit without SP.
