Game goes back to main menu after play

Hey guys,

The issue I’m having is that my game, after launch, will be directed back to the main menu after the game has played for a few seconds. Also, while in-game, I cannot possess my character. I can see that my character (first person) moves around while the main menu is up so what am I missing? I’m completely new to UE4 so any advice would be greatly appreciated. Thank you for your time.

I have attached a couple images from my BP. They’re basic so the seasoned users should be able to resolve this easily!
