SfPdfViewer crash: Cannot access a disposed object. Object name: 'Stream has been closed'.

[Khalid Essaadani]

Hi,

We are using SfPdfViewer (version 19.3.0.55) in our Xamarin.Forms (version 5) application in order to convert the selected PDF file to image, the operation was working fine but recently we had a crash after selecting the PDF file.

The exception says:

Cannot access a disposed object.
Object name: 'Stream has been closed'.

Here is the StackTrace:
