"COM object that has been separated from its underlying RCW cannot be used"

Question

I have a little function in my asp / C# site which exports some data through excel using PIA.

After some research along days about how to use properly all of this, sometimes I'm getting this error:

COM object that has been separated from its underlying RCW cannot be used.

at Microsoft.Office.Interop.Excel.ApplicationClass.set_DisplayAlerts(Boolean RHS)

After that, I always get this another error, but i supose that it's related/caused by the first error:

Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

at Microsoft.Office.Interop.Excel.ApplicationClass.Quit()

I'm feeling quite confused because I tested this in three computers, and works fine in two of them.

The relevant code is the following:

public static class Export{

    public static Application objExcel;
    public static Workbooks objBooks;
    public static _Workbook objBook;
    public static Sheets objSheets;
    public static _Worksheet objSheet;        

    public static Boolean export (DataSet ds, String path)
    {
        try
        {
            objExcel = new Application();
            objBooks = objExcel.Workbooks;
            objBook = objBooks.Add(XlWBATemplate.xlWBATWorksheet);
            objSheets = objBook.Worksheets;
            objSheet = (_Worksheet)objSheets.get_Item(1);
            Range objRange = null;

                
             //Do things . . .

             MergeCells(objExcel, objSheet);
              
             //Do more things . . .

            catch (Exception ex)
            {
                Global.ManageException(ex);
            }
            finally
            {

                if (objExcel != null)
                    objExcel.Quit();
                
                ReleaseComObject(objExcel);
                ReleaseComObject(objBooks);
                ReleaseComObject(objBook);
                ReleaseComObject(objSheets);
                ReleaseComObject(objSheet);
                ReleaseComObject(objRange);
                

            }

RelecaseComObject() is the following:

    private static void ReleaseComObject(object reference)
    {
        try
        {
            if(reference!=null)
                while(System.Runtime.InteropServices.Marshal.ReleaseComObject(reference) > 0)
                {}
        }
        catch (Exception e)
        {
            Global.ManageException(e);
        }
    }

And MergeCells() is something like this:

private static void MergeCells(Application objExcel, _Worksheet objSheet)
    {
        objExcel.DisplayAlerts = false;

        // Do things
        
        objExcel.DisplayAlerts = true;


}

Taking a look to the line of the error, may it be caused by calling objExcel.DisplayAlerts from inside of that function instead the main function? (I would like to try it but I have some limitations to deploy the code many times in the third computer).

How can I manage the code properly to make it safe and avoid this kind of errors?

Thanks in advance.
