Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
I checked the page source, it looks like you are using the Oxygen Builder.
The error is caused by the Oxygen Builder plugin.
The Oxygen Builder team has already identified the issue, this error began occurring in WordPress 5.8 between Oxygen and SEO plugins.

You can try adding the snippet using the Code Snippets plugin, which should fix the issue.
I hope this helps. Looking forward to helping you.
Thanks a lot! It was published by error but your help is invaluable.
PD: I’ve tried it, and really works! Thanks you so much.
