QBFC 10 `sessionManager.BeginSession` System.AccessViolationException

Question

I am getting this QBFC10 error `System.AccessViolationException: 'Attempted to read or write protected memory. This is often an indication that other memory is corrupt.'

The error points to this code sessionManager.BeginSession(@"D:\CompanyFile.qbw", ENOpenMode.omDontCare); below.

If remove the file path @"D:\CompanyFile.qbw" and leave it empty "" it works. But that is not the intention. I need to have the file path there in order for me to run the application even if QuickBooks is not running.

private void BtnQuery_Click(object sender, EventArgs e)
{
    bool sessionBegun = false;
    bool connectionOpen = false;
    QBSessionManager sessionManager = null;

    try
    {
        sessionManager = new QBSessionManager();
        IMsgSetRequest requestMsgSet = sessionManager.CreateMsgSetRequest("US", 10, 0);
        requestMsgSet.Attributes.OnError = ENRqOnError.roeContinue;

        IItemInventoryQuery ItemInventoryQueryRq = requestMsgSet.AppendItemInventoryQueryRq();

        sessionManager.OpenConnection2("", "AppName", ENConnectionType.ctLocalQBD);
        connectionOpen = true;
        sessionManager.BeginSession(@"D:\CompanyFile.qbw", ENOpenMode.omDontCare);
        sessionBegun = true;

        IMsgSetResponse responseMsgSet = sessionManager.DoRequests(requestMsgSet);

        sessionManager.EndSession();
        sessionBegun = false;
        sessionManager.CloseConnection();
        connectionOpen = false;

        String xml = responseMsgSet.ToXMLString();
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message, "Error");
        if (sessionBegun)
        {
            sessionManager.EndSession();
        }
        if (connectionOpen)
        {
            sessionManager.CloseConnection();
        }
    }
}

I also raised this issue with Intuit Developer support awaiting their response. I am hoping anyone here is familiar with QuickBooks API (QBFC).
