Crashes during story dialogues. (Dying Light 2: Stay Human)

I play with a friend in co-op, you can run around the world, but if some kind of dialogue (story / side) starts, then at the moment of choice the game throws a friend out of the session, has anyone encountered this problem? And we don't know what to do. It does not completely kick out of the game, but simply to the main menu, as if there are problems with the Internet, although both have an average download speed of ~ 90-100.
