When you test the game, the message below appears and the game does not work.

Script 'Intro' has finished playing, and there wasn't a follow-up goto command. Consider using stop command in case you wish to gracefully stop script execution.

If you wait a little bit, it will work again, but it's hard to wait every time, so I'd like to know the solution.

It's pretty self-explanatory. End the script with @stop if it doesn't end with @goto.
