Applicationclosingafterupdatingaccessdatabase

I have a form that displays a datagridview via a DataTable. I have a button that opens a new form (EditTask), and it edits the data inside one of my tables in my ms-access database. Whenever I click the "addtask" button inside my EditTask form, my whole applications closes and I do not get any error messages. Here is my code for the save button:

 private void btnAddTask_Click(object sender, EventArgs e)
    {
        ConnectToDataBase();
        OleDbCommand command = new OleDbCommand();
        command.Connection = connection;
        RefreshDBConnection();
        //Saving 10C Club
        if (cboWebsite.Text == "10C CLUB")
        {
            string query = "UPDATE INTO Tasks SET [PLATFORM]=@platform, [TASK TYPE]=@tasktype, [KEYWORD]=@keyword, [LINK]=@link, [PROFILE]=@profile, [10C EMAIL]=@10email, [10C PASSWORD]=@10pass, where id=@id";
            command.Parameters.AddWithValue("@platform", cboWebsite.Text);
            if (radio10cDirectLink.Checked == true)
            {
                command.Parameters.AddWithValue("@tasktype", "Direct Link");
            }
            else
            {
                command.Parameters.AddWithValue("@tasktype", "Keyword");
            }
            if (txt10cKeyword.Text == "ROME")
            {
                command.Parameters.AddWithValue("@keyword", "");
            }
            else
            {
                command.Parameters.AddWithValue("@keyword", txt10cKeyword.Text);
            }
            if (radio10cDirectLink.Checked == true)
            {
                command.Parameters.AddWithValue("@link", txt10cDirectLink.Text);
            }
            else
            {
                command.Parameters.AddWithValue("@link", txt10cHomePage.Text);
            }
            command.Parameters.AddWithValue("@profile", cboProfiles.Text);
            command.Parameters.AddWithValue("@10email", txt10cLoginEmail.Text);
            command.Parameters.AddWithValue("@10pass", txt10cLoginPassword.Text);
            command.Parameters.AddWithValue("@ID", txtID.Text);
            command.CommandText = query;
            command.ExecuteNonQuery();
            RefreshDBConnection();
            connection.Close();
            MessageBox.Show("Task Edited");
            this.Close();
        }
        if (cboWebsite.Text == "DRY GOODS")
        {
            string query = "UPDATE INTO Tasks SET [PLATFORM]=@platform, [TASK TYPE]=@tasktype, [KEYWORD]=@keyword, [LINK]=@link, [PROFILE]=@profile, [10C EMAIL]=@10email, [10C PASSWORD]=@10pass, where id=@id";
            command.Parameters.AddWithValue("@platform", cboWebsite.Text);
            if (radioDGDirectLink.Checked == true)
            {
                command.Parameters.AddWithValue("@tasktype", "Direct Link");
            }
            else
            {
                command.Parameters.AddWithValue("@tasktype", "Keyword");
            }
            if (txtDGKeyword.Text == "ROME")
            {
                command.Parameters.AddWithValue("@keyword", "");
            }
            else
            {
                command.Parameters.AddWithValue("@keyword", txtDGKeyword.Text);
            }
            if (radioDGDirectLink.Checked == true)
            {
                command.Parameters.AddWithValue("@link", txtDGDirectLink.Text);
            }
            else
            {
                command.Parameters.AddWithValue("@link", txtDGHomePage.Text);
            }
            command.Parameters.AddWithValue("@profile", cboProfiles.Text);
            command.Parameters.AddWithValue("@10email", txtDGGoogleEmail.Text);
            command.Parameters.AddWithValue("@10pass", txtDGGooglePassword.Text);
            command.Parameters.AddWithValue("@ID", txtID.Text);
            command.CommandText = query;
            command.ExecuteNonQuery();
            RefreshDBConnection();
            connection.Close();
            MessageBox.Show("Task Edited");
            this.Close();
        }

Here is additional code for opening EditTask form inside my form1:

private void btnEditTask_Click(object sender, EventArgs e)
    {
        if (dataTasks.SelectedRows.Count < 0)
        {
            MessageBox.Show("You must select one user!");
            return;
        }

        DataGridViewRow row = dataTasks.SelectedRows[0]; // We will select first selected row. If there are multiple selected rows we will select just first one

        int uid = Convert.ToInt32(row.Cells["ID"].Value);
        string eplatform = row.Cells["PLATFORM"].Value.ToString();
        string etasktype = row.Cells["TASK TYPE"].Value.ToString();
        string elink = row.Cells["LINK"].Value.ToString();
        string ekeyword = row.Cells["KEYWORD"].Value.ToString();
        string eprofile = row.Cells["PROFILE"].Value.ToString();
        string e10cemail = row.Cells["10C EMAIL"].Value.ToString();
        string e10cpassword = row.Cells["10C PASSWORD"].Value.ToString();
        string egoogleemail = row.Cells["GOOGLE EMAIL"].Value.ToString();
        string egooglepassword = row.Cells["GOOGLE PASSWORD"].Value.ToString();
        string eproxy = row.Cells["PROXY"].Value.ToString();
        //I am using `using` since `Form` is disposable class and instead of later doing sf.Dispose() i use `using`. This way we take care of perfomance
        using (EditTask f3 = new EditTask(uid, eplatform, etasktype, elink, ekeyword, eprofile, e10cemail, e10cpassword, egoogleemail, egooglepassword, eproxy, this))
        {
            f3.ShowDialog();
        }
    }

Please let me know if I can add anything else. Thank you! I'm using C# and Visual Studio btw.
