I have worked with the presentation file shared by you and have experienced NullReferenceException while accessing the presentation. It seems to be an inconsistency in Aspose.Slides. An issue with ID 23684 has been created in our issue tracking system to resolve the issue. This thread has also been linked with the issue, so that you may be automatically notified, once the issue is resolved.
I have requested our development team to share the status of the issue. As soon as some information is shared, I will be obliged to share that with you.
Please accept my apology for the delayed response.
I have requested our development team to share the feedback. They are investigating the issue and once some update is shared, I will be obliged to pass on that to you.
I like to share that unfortunately at the moment the issue is unresolved at the moment. However, I have requested our development team to share the response ASAP. I will share the updates with you accordingly.
I have tested the presentation with Aspose.Slides for .NET 5.3.0 and NullReferenceException is no more there. However, the generated PDF is still having rendering issues. I have updated the development team about the status of the issue.
I have verified from our issue tracking system and like to share that the issue shared has only been partially resolved yet; i.e. the chart on slide 3 is rendered fine but bar chart on slide 2 is rendered. I have shared the findings with our development team by re-investigating the issue using latest available version of Aspose.Slides for .NET 6.3.0. I have requested our development team lead to schedule the issue for further resolution and will share my findings with you ASAP.
