Exception in thread "main" java.lang.reflect.InvocationTargetException using javafx

Question

I'm doing a group project using Java and Javafx on IntelliJ. Javafx had some problems working at first but we managed to make it work again. Then suddently out of nowhere it started to make errors again. I've tried to change the JDK because I thought I had the wrong one, I've changed the version of Javafx and it still made it.

Process finished with exit code 1

Here's the main since for some reasons the error occurs on line 11 in main.

import javafx.fxml.FXMLLoader;

import javafx.scene.image.Image;
import javafx.scene.layout.Pane;
import javafx.stage.Stage;

public class Main extends Application {
    @Override
    public void start(Stage stage) throws Exception {
        Pane root = FXMLLoader.load(getClass().getResource("vueMap.fxml"));
        stage.setScene(root.getScene());
        stage.setResizable(false);
        stage.setTitle("Space Game");
        stage.getIcons().add(new Image("/Sprites/Enemies/YinYang.png"));
        stage.show();
        root.requestFocus();
    }
}

And viewmap.fxml even if I don't think there's anything wrong with it but that's what it's used on line 11.

<?import javafx.scene.layout.Pane?>
