❔ How to disable background worker?

private void Start_Click(object sender, EventArgs e)
        {
            if (started)
            {
                StartButton.Text = "Start";
                started = false;
                backgroundWorker1.CancelAsync();
                InitCheckLocalTimer().Stop();
                InitCheckLocalTimer().Dispose();
            }
            else
            {
                StartButton.Text = "Stop";
                started = true;
                InitCheckLocalTimer().Start();
            }
        }

        private void CheckLocalTimer(object sender, EventArgs e)
        {
            if (!backgroundWorker1.IsBusy)
            {
                backgroundWorker1.RunWorkerAsync();
            }
        }

        private void backgroundWorker1_DoWork(object sender, System.ComponentModel.DoWorkEventArgs e)
        {
            if (!backgroundWorker1.CancellationPending && !e.Cancel)
            {
                Console.WriteLine("TEST")
            }
            else
            {
                e.Cancel = true;
            }
        }
