Package operation error: EBUSY: resource busy or locked

So I'm looking to monetize my game by adding ads after publishing on Android devices. I went to services and I toggled ads to be on and chose that kids under 13 can play this game as it is a platformer and so I wouldn't want bad ads to show as kids would want to play the game. But as soon as I turned it on, the blue light is still on and everything seems to be fine but I get that error on my console that shows what I got on this title of my thread and so I'm guessing it would mean that adding ads wouldn't work. Now I didn't actually add any code to implement those ads into the game but I know that that wasn't supposed to happen and so I came here to ask for help about if there's anything I can do to make it work. Thank you
