Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.
Could you please make sure that you are not connecting to Google Search Console via a domain property but rather a URL prefix and that you have verified the correct version of your website on the Google Search Console (HTTP or HTTPS, www or non-www)?
Also, please ensure that you have verified your email/account as the owner of the property. Go to your Google Search Console > Settings > Users and permissions

Once done, try reconnecting your website in Rank Math > General Settings > Analytics > Reconnect.
Let us know how this goes.
Thank you.
