c# Help (MySqlexception was unhandled, Fatal error encountered during command execution.) : i try to add some values to table(tbllogs) after loging in, but i got an error

here's my code

    if (ctr == 1)
            {
                Data.con.Open();
                MetroMessageBox.Show(this, "Login Success!", "Welcome!", MessageBoxButtons.OK, MessageBoxIcon.Information);
                MySqlDataAdapter da = new MySqlDataAdapter("Select * From dbinfo.tbluser where UserName = '" + txtUser.Text + "' and UserPassword = '" + txtPass.Text + "'", Data.con);
                DataTable dt = new DataTable();
                da.Fill(dt);

                Data.UserID = dt.Rows[0][0].ToString();
                Data.UserName = dt.Rows[0][1].ToString();
                Data.UserLevel = dt.Rows[0][3].ToString();

                string SaveStr = "Insert into dbinfo.tbllogs (LogsUser, LogsPassword) Values (@LogsUser, @LogsPassword)";
                MySqlCommand SaveCmd = new MySqlCommand(SaveStr, Data.con);

                //SaveCmd.Parameters.AddWithValue("@LogsID", Data.UserID = dt.Rows[0][0].ToString());
                SaveCmd.Parameters.AddWithValue("@LogsName", txtUser.Text);
                SaveCmd.Parameters.AddWithValue("@LogsPassword", txtPass.Text);
                //SaveCmd.Parameters.AddWithValue("@LogsLevel", Data.UserLevel = dt.Rows[0][3].ToString());
                //SaveCmd.Parameters.AddWithValue("@LogsDateIN", timelabel.Text);

                SaveCmd.ExecuteNonQuery();
                Data.con.Close();
                LoadData();
                

                Menu frmMenu = new Menu();
                frmMenu.Show();
                this.Hide();
            }

i tried changing the code ` SaveCmd.Parameters.AddWithValue("@LogsName", txtUser.Text);` to ` SaveCmd.Parameters.AddWithValue("@LogsName", Data.Password = dt.Rows[0][2].ToString()));` but didn't work either.


i will provide more code if this isn't enough, Thanks in advance!
