A reason for the crash can be a change to the ActiveX API, which added an additional paramater.Sometime around late 2016, Microsoft updated their ActiveX API, and these changes were automatically pushed to users of Microsoft Office 365 in Version 1609. An extra parameter called WorkIdentity was added to the ActiveX function call SaveAs, which is an Excel Workbook method.
