I can't get the game to show on streamlabs

[Ellie925]

I remember streaming with it once but after then it never once worked, the game isn't marked as a game for streamlabs for me. I've had issues with the game at some point where the game was tinted green, so it could be connected to that, but I've fixed that and it still doesn't work. I don't like using the screen capture since it puts a yellow boarded on it. Can someone help me out? Sorry for being very vague, but that's all I can say since that's the only problem.
