Playing on an older PS4. The game has random blue screen lockups but this is different. When I approach the north gate of Lunden, it's supposed to start an animation. I never get that far. It goes into a black screen with the 'activity' symbol in the lower right-hand corner for about 20 seconds. After that I can see Eivor and can move the camera but nothing else. I cannot move, I can't activate my menu, abilities or fast travel. I can only pause and reload the game. This has happened 6 times. I have checked to see that I'm running the most current version of the game and performed multiple restarts. I've done all the non-story content in Lunden but cannot start this quest.
