There is an existing topic about using the BindToClose function and DataStore causing issues with studio. I’m not updated with the topic, so I’m not sure if it has been solved. Looking at what your output says, the error is pretty similar to what other have said about using BindToClose.
Edit:
In my current understanding, the error occurs when studio tries to close a running server, but a script is trying to process/do more after the game is meant to shutdown. This is because of Yielding Functions, which is common with data stores and wait()
