Hello NAPS2 developers!

At first - Thank you a lot for the creation of such fantastic freeware tool! We love it!

To the point - With the newest version we started getting following error message when doing batch scan (tens of pages) on our Windows 10 Pro 64-bit desktop PC:

--- cut ---
NAPS2.Scan.Exceptions.ScanDriverUnknownException: An error occurred with the scanning driver. ---> System.Runtime.InteropServices.COMException: Error HRESULT E_FAIL has been returned from a call to a COM component.
