VS Code中JavaFX程序运行问题

环境信息

JDK版本：17
JavaFX SDK版本：17.0.9
开发环境：VS Code

已完成配置

已将JavaFX相关JAR文件添加至VS Code偏好设置
已配置launch.json文件，内容如下：

{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
    {
        "type": "java",
        "name": "Current File",
        "request": "launch",
        "mainClass": "${file}"
    },
    {
        "type": "java",
        "name": "App",
        "request": "launch",
        "mainClass": "App",
        "projectName": "testfx_1e12e64c",
        "vmArgs": "--module-path \"C:\\Program Files\\Java\\javafx-sdk-17.0.9\" --add-modules javafx.controls,javafx.fxml"
    }
]
}

待运行代码

import javafx.application.Application;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class App extends Application {
     @Override
     public void start(Stage primaryStage) throws Exception{
        Parent root = FXMLLoader.load(getClass().getResource("testfx.fxml"));
        primaryStage.setTitle("Hello World");
        primaryStage.setScene(new Scene(root, 400, 300));
        primaryStage.show();
     }

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