Hi support,

Opening of a PPTX document with a modern comment on an object fails with error (see below).
NB: A new document with a comment using the new button on the right comments section (add comment to doucment) it does work. Aspose version: 22.5

We are using code:

using (Presentation presentation = new Presentation(filePath))
{
    ...
}

Error:
