Weird bug I can't seem to fix

Right now, I’m remaking a bunch of games I play at school with my friends in makecode arcade (see wallball), and I’m recreating ball tag. But for whatever reason I can’t find it gives an error when you try to play the game. I tried everything from asking chatgpt to changing a ton of stuff, and the error wasn’t even there before I added an overlap block. It just suddenly decided to break my game.
