Hello,
Thank you for contacting the support and sorry for any inconvenience that might have been caused due to that.
Sorry for the issue you are facing.
I tried to use Rank Math with your site language in a local installation and everything worked fine.
Assuming you are using the latest version of all the plugins and the themes (please update if not yet), it would seem like a conflict with one of the plugins or the theme you are using.
To determine that, please follow this troubleshooting guide:

Please let us know if you find the culprit.
Only the site admin would know and your users won’t be affected by this troubleshooting.
Looking forward to helping you.
