Local Multiplayer not working after build

Hey guys,

I’m trying to get a two player local play game work-- in engine, it’s fine and it all works perfectly, but the moment it’s built the second player doesn’t work.

Here are images of the spawn function in the game mode and the player character’s blueprint. When the game begins it create’s a player with the function of the same name, then feeds into the ‘Spawn Player’ Function.

Is there any reason that it shouldn’t be working? Any help or redirects to a similar topic with a fix would be appreciated.
