Hello,
Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
Could you please try to roll back your Rank Math version to version 1.0.65? You may do that here: WordPress Dashboard > Rank Math > Status & Tools > Version Control.
See if that fixes your issue.
However, I tested the URL with https://search.google.com/test/rich-results, the URL is validated without any errors.
Please note that the Structured Data Testing Tool is being deprecated. For validating structured data for Google Search, Google now recommends using the Rich Results Test for more accurate and actionable feedback.
For more information on this deprecation, read this blog post.

With that said, we have identified this problem and we are now escalating this to our developers.
We are looking forward to helping you.
