They didn't give any info about the error, so I was confused for a while, but here is the fix:

Change in MainWindow.fxml: <AnchorPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="600.0" prefWidth="400.0" xmlns="http://javafx.com/javafx/8.0.171" xmlns:fx="http://javafx.com/fxml/1" fx:controller="MainWindow"> To <AnchorPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="600.0" prefWidth="400.0" xmlns="http://javafx.com/javafx/8.0.171" xmlns:fx="http://javafx.com/fxml/1" fx:controller="duke.gui.MainWindow"> (Add the package name)

Hope this helps anybody facing the same issue!

It will depend on where everyone puts their files and how they structure their packages, but generally change the value for fx:controller to your own package path to MainWindow and it should work fine.
