Fail to remove macro from xlt using Aspose Cells 19.7 for NET


Hi there,
I using the following code snippet to remove macro from xlt file.

 using(var inStream = new FileStream(inputXltFile, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
        var opt = new LoadOptions
                                MemorySetting = MemorySetting.MemoryPreference

        var workbook = new Workbook(inStream, opt);
        try {
        catch (Exception e)

With Apsose Cells 19.2, the macro can be removed successfully. But with Aspose Cells 19.7, it throw an exception with message ‘Object reference not set to an instance of an object.’ (71.5 KB)
