The process cannot access the file will occurs when I use Document.Save method

Hi,
Not able to save a pdf file if it its size is more than 400MB.(with Aspose.pdf version 20.3)

The process cannot access the file ‘C:\users\Desktop\Big PDF\402mb.pdf’ because it is being used by annother process.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy, Boolean useLongPath, Boolean checkHost)
at System.IO.FileStream…ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize)
at Aspose.Pdf.Document.PdfFileInfo.Save(String outputFileName)

some code as follows:

var pdfSign = new PdfFileSignature(_document);
var names = pdfSign.GetSignNames();
foreach (var name in names)
{
    pdfSign.RemoveSignature(name);
}
_document.Save(OutputFile);    // outputfile is the path of target file

Is Save() method have some problems?
Thanks in advance for help!

There is no such known issue with Save() method. However, could you please share a sample console application which is able to reproduce the issue you are facing. We will test the scenario in our environment and address it accordingly.
