Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for the delay and for any inconvenience this issue may have caused you.
It seems like new tables are not getting created in the Database or some old plugin has left an incorrect entry.
If you’re still unable to login into your WordPress dashboard, please deactivate Rank Math temporarily by renaming the seo-by-rank-math folder in your website’s root directory – /wp-content/plugins/
Once you have access already, please follow the steps in this link:

Note: You can skip the section For Advanced Users
After doing so, please clear your website’s cache and rename the folder name to seo-by-rank-math in your File Manager then activate Rank Math on your WordPress dashboard.
I hope that helps. Thank you, and looking forward to your update.
