Playable Character Spawns ONLY When Possess Is Clicked

I can not get my player start to work for some reason. The level starts and im in fly mode. There are no characters on the map but there is a player start. When i click the posses button it will spawn me a playable character. What did i mess up? Im not sure what actually started this problem because i created a new map and added a main menu at the same time. The main menu works fine but if i load into the first level or if i load the first level to start i have the same issue so i dont believe the menu messed it up.

Game Mode Override + Default Pawn Class are both set to ThirdPersonCharacter

UPDATE:
So i just found out this is ONLY wile in the editor and using the play button. If i launch the game via the launch button everything works fine. Very strange.

This may be a very late answer, forgive me. Did you set the “Auto Player Possess” on Character properties to “Player 0”?
