JavaFx: txt.setFont(new Font("Arial", 30)); is not working on windows 10.

I have tried other fonts too but still they didn't work. And i did not find any solution on the internet. Thank you for your time!

package sample;

import javafx.application.Application; import javafx.fxml.FXMLLoader; import javafx.scene.Group; import javafx.scene.Parent; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.scene.control.Label; import javafx.scene.control.TextField; import javafx.scene.layout.GridPane; import javafx.scene.layout.VBox; import javafx.scene.text.Text; import javafx.stage.Stage;

import java.awt.*;

public class Main extends Application {

@Override
public void start(Stage primaryStage) throws Exception{
    //Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
    Group root = new Group();
    Text txt = new Text("Sup?");
    txt.setFont(new Font("Arial", 30)); // THIS IS THE LINE!!!!
    Label label = new Label("Name:");
    TextField nameFld = new TextField();
    GridPane grid = new GridPane();
    grid.add(label, 0, 0);
    grid.add(nameFld, 1, 0);
    grid.setHgap(20);
    Button btn = new Button();
    grid.add(btn, 1,1);
    //grid.setGridLinesVisible(true);
    btn.setText("Say Sup!");
    btn.setOnAction(event -> System.out.printf("Sup %s!%n",
            nameFld.getText()));
    txt.setY(50);
    VBox box = new VBox();
    box.getChildren().addAll(txt, grid);
    root.getChildren().add(box);
    primaryStage.setTitle("Sup");
    primaryStage.setScene(new Scene(root, 300, 275));
    primaryStage.show();
}


public static void main(String[] args) {
    launch(args);
}

}

And this is the output error generated by the code:
