I check this article:

And I was ejecute Health Check and the result was:
Verifying a Theme or Plugin Conflict
1 With all plugins and your theme disabled, try reproducing the issue.
(a) If you still have the issue, your WordPress setup is the root of the problem.
And now?
Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
The following JS error is reported on the console with all other plugins deactivated:
Uncaught TypeError: rankMath.stopwords.includes is not a function
This might be an environment problem, could you please clone your site to a different server/local install and check if the same error will be reproduced?
Looking forward to helping you. Thank you.
