Revit Print pdf error

Anonymous — Tue, 24 Dec 2019 07:44:58 GMT
Has anyone ever encountered such a problem?
I used revit2017 API to write a function of printing sheets to PDF in batch.But sometimes there's a mistake like this.
Revit2017 crash after clicking close button.
Here is My Code:
Tips:Adobe PDF used.
using (RevitDB.Transaction transaction = new RevitDB.Transaction(revitDoc, "PrintPdf"))
            {
                transaction.Start();

                RevitDB.PrintManager printManager = doc.PrintManager;
                printManager.PrintRange = RevitDB.PrintRange.Select;
                RevitDB.ViewSheetSetting viewSheetSetting = printManager.ViewSheetSetting;
                viewSheetSetting.CurrentViewSheetSet.Views = printableViews;
                viewSheetSetting.SaveAs("MyViewSet");          
                                                                
                if (printManager.IsVirtual == RevitDB.VirtualPrinterType.AdobePDF)
                    printManager.CombinedFile = false;
               
                int IndexFlag = 0;

                foreach (RevitDB.View view in printableViews)
                {
