PPT file failed to load and throw exception "An entry with the same key already exists"


When trying to load a ppt file, an exception was thrown: “An entry with the same key already exists”. I’m using Aspose Slides .Net 18.9.0.

Below is my sample code:

Presentation pres = new Presentation(“An_entry_with_the_same_key_already_exists.ppt”);

I had tried to check this error on the Internet and found out that this issue happened before and is fixed in ticket SLIDESNET-37431 for Aspose.Slides .NET 16.8.0, but now, it didn’t work with Aspose Slides .Net 18.9.0.

This is the sample: An_entry_with_the_same_key_already_exists.zip (629.9 KB)

Please help and give me some advice for this issue.
