The program terminates unexpectedly when I start another process

Question

My program exists suddenly, and I cannot find the cause, but I know which parts of the code are causing this problem. I will try to explain what happens ...

First of all, I use the following namespaces in my window form in addition to the general ones:

using System.Diagnostics;
using System.IO;
using System.Data.OleDb;

I have a custom function that retrieves the current identifier of an auto-increment string by searching for the maximum ID and incrementing it by one:

void getCurrentQuestionNo()
{
    //calculate current questionNo based on DB Info
    classDataLayer DL = new classDataLayer();
    OleDbCommand cmd = new OleDbCommand();
    cmd.CommandText = "SELECT MAX([questionID]) FROM questions";
    DataSet ds = DL.select(cmd);
    questionNo = Convert.ToInt32(ds.Tables[0].Rows[0][0]) + 1;
}

This function is run inside the form_load function to set a global variable called questionNo for later use.

I also have the following code to open an instance of a Microsoft Word application. This code is placed inside the button click event:

try
{
    //copy an instance of empty question template to Temp folder
    File.Copy(@"Templates\EmptyQuestion.docx", @"Temp\TempQuestion.docx", true);
    //launch ms-word to open the document
    ProcessStartInfo startInfo = new ProcessStartInfo();
    startInfo.FileName = "WINWORD.EXE";
    startInfo.Arguments = @"Temp\TempQuestion.docx";
    Process.Start(startInfo);
}
catch (Exception ex)
{
    MessageBox.Show(ex.Message, "error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
