Factorio crashes on Player Connection.

Whenever I try to start a multiplayer game with my friend, he tries to connect and my game crashes soon after. Then he gets an error message saying he couldn't connect.

*Did more testing and when the crash error comes up the game still runs but when I select yes or no to save the log report it crashes.
