Thanks for providing us template file.

After an initial test, I am able to observe the issue as you mentioned by using your sample code with your template file. I found that Excel file becomes corrupt (MS Excel prompts error messages when opening the file into it) after refreshing the PivotTable:
Sample code:


    Workbook workbook = new Workbook("e:\\test2\\Testsheet.xlsx"); 
    Worksheet sheetOverview = workbook.Worksheets["Overview"];
