NullRefException When Opening Some PPTX Files

We are getting a NullReferenceException when opening some files, others are ok. An example of a file that errors is attached and we've narrowed it down to the image.

- cutting and pasting the image back into the PPTX as a PNG stops the error from happening

- copying the entire slide into a new blank presentation also stops the error from happening

We have several thousand PPTX and we can't perform this work around for them all. Can you discover why the PPTXs are failing to load?

Hi David,

Thanks for considering Aspose.Slides.

I have worked with the presentation file shared by you and have been able to observe the issue. An issue with ID 31396 has been created in our issue tracking system to resolve the issue. However, there is no issue happening while accessing presentation using Aspose.Slides for .NET 5.5.0. Please us the specified version for the time being and it can be downloaded from here.

We are sorry for your inconvenience,

The issues you have found earlier (filed as 31396) have been fixed in this update.
