Csharp C#无法让WinForm进度条生成动画错误跨线程操作无效

New to c#. I have a winform with a combobox, button and progress bar. On the button click event text is taken from the textbox and used in a sql query. While this query is running, I would like a progress bar (marquee - does not need to show % complete) to animate, when the query is complete I would like it to stop.
I have tried the below code but get the error:

‘跨线程操作无效:控件’cbTest‘从 线程而不是在其上创建它的线程.

private System.Windows.Forms.ProgressBar _progressBar;

public Test()
{
    InitializeComponent();
    _progressBar = progressBar;
}

private void Form1_Load_1(object sender, EventArgs e)
{
    _progressBar.Style = ProgressBarStyle.Marquee;
    _progressBar.MarqueeAnimationSpeed = 0;
}

public async void btn_Click(object sender, EventArgs e)
{
    await Task.Run(() => GetValues(_progressBar));
}

private void GetValues(System.Windows.Forms.ProgressBar progressBar)
{
    progressBar.Invoke(new System.Action(() =>
    {
        progressBar.MarqueeAnimationSpeed = 30;
    }));

    Sql.SqlQuery("exec Test..sp_Test " + cbTest.Text);

    progressBar.Invoke(new System.Action(() =>
    {
        progressBar.Style = ProgressBarStyle.Blocks;
        progressBar.Style = ProgressBarStyle.Marquee;
        progressBar.MarqueeAnimationSpeed = 0;
    }));
}

public static void SqlQuery(string queryString, string connectionString = "Data Source= Test; Initial Catalog = Test; Integrated Security = True")
{
    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        SqlCommand command = new SqlCommand(queryString, connection);
        command.CommandTimeout = 300;
        command.Connection.Open();
        command.ExecuteNonQuery();
    }
}
