Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
Please check if you are using a Firewall, as it may prevent saving the changes.
If you are using a Firewall, please whitelist this route:
/wp-json/rankmath/v1/updateMeta
Whitelisting the route should fix the issue.
You can check this link for more information:

I hope this helps. Looking forward to helping you.
Hello, I have found the problem.
The Rank Math plugin is not ready to work with the latest version of PHP 8.0.19. When downloading the PHP version the plugin works and saves all changes perfectly.
Thanks for the information about the firewall.
Hello,
Glad that everything has been sorted out. If you have any other questions in the future, know that we are here to help you.
Thank you.
