Images in Word converting to blank boxes

We are using Aspose.Words 21.9.0 and are having troubles where an image in Word are showing up as blank boxes in the PDF generated. I understand that this was an issue that has been addressed in 21.12 (Conversion from Word to PDF doesn't include image) however the question I have is if we should update to 21.12 or if there were any issues moving directly to a newer release?

@mikefields There should not be any issues with upgrading to new version of Aspose.Words. All changes made in newer versions are described in our release notes.
Could you please attach your source and output documents here for testing? I will check the conversion with the latest version and let you know how it goes.

Here is an example of the images that were blank with the conversion to the PDF.

@mikefields With the latest 22.4 version of Aspose.Words the document is converted properly.
