Hi Pauline,
Thanks for getting in touch with us.
Please make sure that you have verified the correct version of your website on the Google Search Console (http or https, www or non-www).
Then, please make sure that the Google account you used to connect your Google Search Console profile is the same one you have used to verify your domain on GSC.
If it still doesn’t work, we have found that using a different Google account to verify your domain and connect your website usually works. Or, you can try using the Google Site Kit if it still won’t work and disable the Search Console inside Rank Math by going to WordPress Dashboard > Rank Math > Dashboard
I hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
