JavaFx InvocationTargetException Exception Chargement d'une fenêtre

Question

J'ai un projet avec 2 fenêtres, le premier paramètre d'une passe à la seconde, mais lors de l'exécution du projet, la classe principale ne déjeune pas la fenêtre, à la place j'ai cette exception:

Exception in Application start method java.lang.reflect.InvocationTargetException

voici mon code principal:

@Override 
public void start(Stage primaryStage) throws IOException { 
    Parent root = FXMLLoader.load(getClass().getResource("Choices.fxml")); 
    Scene scene = new Scene(root); 
    primaryStage.setScene(scene); 
    primaryStage.setTitle("Tic Tac Toe"); 
    primaryStage.getIcons().add(new Image("img/icon.png")); 
    primaryStage.setResizable(false); 
    primaryStage.show(); 
} 

J'ai lu tous les messages sur InvocationTargetException mais il ne semble pas le même problème, je ne peux pas comprendre où est l'erreur, je l'ai le même code sur un autre projet et ça marche (désolé je suis nouveau avec javaFx, c'est juste mon projet de cond).
