Windows forms зависает при нажатии кнопки большую часть времени

---

I am working on a windows application which freezes most of the time on button click events on Home Page. Please find the code below for your reference. Thanks

using System;
using System.Windows.Forms;

namespace FileMigrationAgen
{
    public partial class HomePage : Form
    {
        public HomePage()
        {
            InitializeComponent();
        }

        private void tableLayoutPanel4_Paint(object sender, PaintEventArgs e)
        {

        }

        private async void button1_Click(object sender, EventArgs e)
        {
            SharepointMigration sharepointMigration = new SharepointMigration();
            sharepointMigration.Show();
            this.Hide();
            }

        private async void button2_Click(object sender, EventArgs e)
        {
            OneDriveMigration oneDriveMigration = new OneDriveMigration();
            oneDriveMigration.Show();
            this.Hide();            
        }


        private void HomePage_FormClosed(object sender, FormClosedEventArgs e)
        {
            Application.Exit();
        }
    }
}

Что я уже пробовал:

Попробовал добавить закрытое событие формы в случае, если потоки не были утилизированы должным образом, но это не помогло.
