Cannot Open .pptx file using File Preview Macro

Summary

test3.pptx are two identical slides with different extension test.ppt. (Content was removed because it contains company's info)
While uploading both files to Confluence, File preview macro won't able to preview the .pptx file, but it works for the .ppt file.

These error shown in the logs :

Caused by: class com.aspose.slides.p6a2feef8.pbdb106a0.cw: Unknown char: c

Caused by: class com.aspose.slides.p6a2feef8.pbdb106a0.do: Version of TrueType font is incorrect: 2600468736, expected 65536 for v1.0

Environment

Error persist in the latest version of Confluence Server. However this error is not reproducible in Confluence On Demand (Cloud)

Workaround

The only available workaround at the moment is to convert the pptx file to ppt and use it in Confluence instead of the pptx.
