powerpoint with arabic english slides crashes while creating pdf adobe 2020

I am noticing a sudden change in the way Adobe (2020) handles multiple languages in a document.
If the document contains multiple languages, especially RTL ones (Arabic, Urdu, Persian, etc) it fails to create PDF and the Powerpoint and Word crashes without creating the pdf.

Did some online research and found nothing as a credible solution.

Would appreciate your quick feedback.

thanks,

Atif
