Hello,
Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
From the error, it seems your site is missing required table. Could you please recreate the table by following these steps:
1. Update to the latest version of Rank Math Free & PRO
2. Ensure that the Advanced Mode is selected:

3. Re-create tables by clicking WP Dashboard > Rank Math > Status & Tools > Database Tools and click the Re-create database Table button.

If the issue persists, please let us know. We are looking forward to helping you.
This worked. Thanks so much!
