Quest (Mystery) Horn of Ragnar in Gloucestershire (Assassin's Creed: Valhalla)

Friends, such a problem. I went through almost all the zones and did not encounter any problems. And then I come to this quest, I speak with the NPC, we start to search the house, the owner of the house comes, the cutscene begins, then the choice with whom to fight (with the thief or the owner of the house). And that's all. As I saw on YouTube, the fight is about to begin. And my NPCs stand motionless and that's it. The quest does not continue. Already replayed the last couple of hours, again reached this place and nifiga ... did anyone come across?
