Invalid URI exception in Slides for .Net

We are seeing the exception below consistently for a particular .pptx file. Unfortunately the file contains confidential information so I cannot share it with Aspose. I tried removing the confidential information from the file but then the exception no longer happens.

Here is the stack trace:

Exception message:
Invalid URI: The format of the URI could not be determined.

Exception stack trace:

Hi Shane,

I have observed the stack trace shared by you but in order to resolve the issue, we need the source presentation that is throwing exception. Please share the presentation file by making this thread post private or by sending private message. Please share with us, when you have shared the presentation. We appreciate your cooperation in advance.

Thanks and Reagards,
