Bug Assassin's creed Syndicate. Black screen (Assassin's Creed: Syndicate)

When you start a mission in DLC, the "Last Maharaja" screen turns black and hangs a download icon, with the mini card displayed, and all the tags on it, including the player's tag, current target, and enemies. And I can even control the invisible Jacob. Tried to restart five times, the game starts from the same moment and nothing changes. Waited for more than an hour that the game will get loaded - nothing changes. What to do? It's been so long, all the dopas, except for this branch and such a bummer. Maybe somehow you can save roll back to the previous point? Or a mission to finish the code, at least something?! ESC and the map don't work, F keys - yes, I can even turn on a replay of some completed mission, but at the end of all the same. I saw a post with the same problem, but I can't do it.
