Hi Visvesvar,
If you add
AnnotationAdded event, then the issue occurs. I modified your example as shown below.

{
byte[] byteArray = System.IO.File.ReadAllBytes("wwwroot/Data/Sample.pdf");
string base64String = Convert.ToBase64String(byteArray);
await pdfviewer.LoadAsync("data:application/pdf;base64," + base64String, null);
}
protected async void onAnnotationAdded(AnnotationAddEventArgs args)
{
//var data = await pdfviewer.ExportAnnotationsAsObject();
}
}
