When I run my code setLayout is not working with JPanel

I keep getting the errors that:

The method setLayout(LayoutManager) in the type JFrame is not applicable for the arguments (GridLayout)
The constructor GridLayout(int, int) is undefined

When I look as to why it says that:

The method setLayout(LayoutManager) in the type Container is not applicable for the arguments (GridLayout)

and

Is anyone familiar with Swing?

Code:

public class YoutubeSwing extends MainSceneSwing{


    public static JFrame frameTwo = new JFrame();
    public static JPanel topPanel = new JPanel();
    public static JPanel secondPanel = new JPanel();
    public static String songTitle;
    public static String artistName;


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

    public static void runSimulation() {
        setUp();
    }

    public static void topPanel() {
        topPanel.setLayout(new FlowLayout());
        JLabel title = new JLabel("Not-ify", JLabel.CENTER);
        title.setForeground(Color.BLUE);
        title.setFont(Title);
        topPanel.add(title);
    }

    public static void secondPanel() {
        secondPanel.setLayout(new FlowLayout());
        JLabel subtitle = new JLabel("Youtube Music Player", JLabel.CENTER);
        subtitle.setFont(Text);
        secondPanel.add(subtitle);
        JLabel disclaimer = new JLabel("We may place adds before your music so that we can generate some revenue. Please note that we are starving students.", JLabel.CENTER);
        disclaimer.setFont(ButtonText);
        secondPanel.add(disclaimer);
    }

    
    public static void setUp() {
        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(new Dimension(WIDTH, HEIGHT));
        frame.setTitle("Not-ify");
        frame.setLayout(new GridLayout(4,1));

        topPanel();
        secondPanel();

        JPanel thirdPanel = new JPanel();
        secondPanel.setLayout(new GridLayout(4, 1));
        thirdPanel.setLayout(new GridLayout(4,1));
        JTextArea artist = new JTextArea(
                "Please enter the artist of your choice: ");
        JTextArea artistAnswer = new JTextArea(
                "Drake");//**TODO Uncheck */
        JTextArea song = new JTextArea(
                "Please enter the song of your choice: ");
        JTextArea songAnswer = new JTextArea(
                "One Dance");//**TODO Uncheck */

        artist.setEditable(false);
        artistAnswer.setEditable(true);
        song.setEditable(false);
        songAnswer.setEditable(true);

        
        thirdPanel.add(artist);
        thirdPanel.add(artistAnswer);
        thirdPanel.add(song);
        thirdPanel.add(songAnswer);


        JButton start = new JButton("Start");
        ActionListener startListener = new YoutubePlayerButtonListener(start,artistAnswer,songAnswer);
        start.setForeground(Color.GREEN);
        start.setFont(Subtitle);
        start.addActionListener(startListener);

        frame.add(topPanel);
        frame.add(secondPanel);
        frame.add(thirdPanel);
        frame.add(start);

        frame.pack();
        frame.setVisible(true);
    }


    
    public static void start(String artistName, String song, String lyrics, String url, String youtubeLink) {
        // Set up screen
        frameTwo.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frameTwo.setSize(new Dimension(WIDTH, HEIGHT));
        frameTwo.setTitle("Not-ify");
        frameTwo.setLayout(new BorderLayout());

        JPanel leftPanel = new JPanel(); 
        leftPanel.setLayout(new GridLayout(2,1));

        JLabel nowPlaying = new JLabel("Currently Playing: " + song + " by " + artistName);
        nowPlaying.setAlignmentX(JLabel.CENTER_ALIGNMENT);
        leftPanel.add(nowPlaying);
        
        JTextArea scrollLyrics = new JTextArea(lyrics);
        scrollLyrics.setAlignmentX(JTextArea.CENTER_ALIGNMENT);
        scrollLyrics.setEditable(false);
        JScrollPane scroll = new JScrollPane(scrollLyrics);
        scroll.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);
        scroll.getViewport().setView(scrollLyrics);
        leftPanel.add(scroll);


        JFXPanel youtubePlayer = new JFXPanel();
        Platform.runLater(new Runnable() {
            @Override
            public void run() {
        //Youtube panel
        WebEngine engine;

        WebView view = new WebView();
        engine = view.getEngine();

        engine.load(youtubeLink);
    
        youtubePlayer.setScene(new Scene(view));
        }});

        frameTwo.add(leftPanel, BorderLayout.CENTER);
        frameTwo.add(youtubePlayer, BorderLayout.SOUTH);
        frameTwo.pack();
        youtubePlayer.setVisible(false);
        frameTwo.setVisible(true);
    }
}

Thanks in advance for taking a look. It was working one second and then boom.
