Simulate resetting to spectator cannot play

This is probably something simple, I had set up a game mode and character class, set up inputs for moving and could play the simulation with the character moving fine, I was setting up some more inputs and now whenever I click play the camera ignores my character and just simulates but with a spectator.

I tried creating a new level, new characterbp from scratch and even a basic character will not show up in play with nothing in it. and gamemode bp but still I cannot play the game.

Any ideas what it is, it must be something stupid I have done.
