Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.
In this case, please check if there’s some security rule inside your .htaccess file that may prevent saving the settings.
You can also use the default .htaccess file from here: https://wordpress.org/support/article/htaccess/
Please do take a complete backup of your website before modifying your .htaccess as it is a sensitive file.
If the issue persists, you may also check if your website has the ModSec
(ModSecurity) feature enabled on your server, as it can block some bots from accessing your site.
Let us know how this goes.
