Hi, I'm suffering from a BUG/GLITCH in the game "Assassin's Creed: Rogue"

What happens is: On a mission at Davenport Mansion, after the mission in Portugal - Lisbon, when I approach the restricted area of the mansion, the game image stops, and after a few moments the screen goes completely black. I can't control anything, but the sounds still go on.

1. The conclusion when this problem occurred to me is 14%;
2.The DLC "Time saver - Technology Pack" is active in the game;
3. The bug sometimes stops, but it comes back seconds before talking to Achilles.

I've tried everything to solve it. I've deleted my saved game and started again, I've tried running the game as an administrator, I've already tested the settings in DXCPL, I've uninstalled and re-installed the game, but this problem always comes back to me.
