I get a strange error when running mongod on terminal

So I noticed that when I run mongod on visual studio code I get this: Failed to set up listener: SocketException: Address already in use, which is strange since I closed all my terminal windows, how can I resolve this?

See this StackOverflow answer on the subject of this bug: Failed to set up listener: SocketException: Address already in use,

My guess is that you're already running mongo. Two things can't both run on the same port.
