Hello,
Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
Are there any steps to trigger that error?
It would also be nice to check if there are other plugins that might be causing conflict with Rank Math.
To determine that, please follow this troubleshooting guide:

Here is a video you can follow as well: https://www.youtube.com/watch?v=FcIWRhcUP2c
Only the site admin would know and your users won’t be affected by this troubleshooting.
If the issue persists, please edit the first post on this ticket and include your WordPress login in the designated Sensitive Data section.
Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:

Hello,
If we are not able to debug the issue over the dashboard, it may be very difficult for us to provide a solution.
Are you able to provide a staging website instead? If so, please create one, replicate the issue there and provide the admin login here.
You can use this plugin to create a staging environment for your site:
https://wordpress.org/plugins/wp-staging/
We are looking forward to helping you.
