The document is attached:

@GaryO

You reported an InvalidOperationException that occurs only when you set

doc.LayoutOptions.RevisionOptions.ShowInBalloons = ShowInBalloons.FormatAndDelete;

The ShowInBalloons enumeration does include the FormatAndDelete value , and this setting appears in other code examples .

What to try

  1. Test other balloon options
// Try a different enum value
doc.LayoutOptions.RevisionOptions.ShowInBalloons = ShowInBalloons.Format; // or ShowInBalloons.None

If the document converts successfully, the problem is isolated to the FormatAndDelete mode.

  1. Create a minimal reproducible sample
  • a small .docx containing at least one tracked format change and one tracked delete,
  • the same code that loads the document, sets ShowInBalloons = FormatAndDelete, and saves to PDF.
    Attach the sample (or a zip) to this thread.
  1. Provide the Aspose.Words version you are using (e.g., 23.9, 24.1, etc.) so we can check whether this behavior is version‑specific.

Work‑around (if you need the PDF now)

Use ShowInBalloons = ShowInBalloons.Format or ShowInBalloons = ShowInBalloons.None to render revisions without triggering the exception.

Please share the version number and a minimal repro file, and we’ll continue the investigation here.
