It Takes Two - "The other player has left the session"

Hey @Zablazer2112 Thanks for the additional info. 

Does this happen when sending an invite, or when you try to load a specific level? Also, are you both on Steam?

When you have a moment we could give the following a try first, if you haven't already. 

1. Run the System File Checker tool, then Check for Windows and GPU updates
2. Troubleshoot your connection to EA games
3. Check if any background applications are stopping the EA app or your game.
