Interface issue (Assassin's Creed: Syndicate)

At the moment where it was necessary to kill Jack the Jumper, everything suddenly disappeared from the screen, only the picture itself remained. There is no navigator, no icons to indicate switching between weapons, no life indicator above the head of enemies.
I checked everything in the settings - it stands as it was.
The game doesn't screw up in any way, everything just disappeared.
What to do?
