Search Console Property – Error on Submission

Good morning.

I have been trying to set up Rank Math fully on my website, and am continually running into an issue when linking the Search Console Property. Can you please help, I have tried the process more times than I care to admit with no success.

Details:
I have run thru the Easy and Advanced Setup Process multiple times, so I will just focus on the Easy process here. I have ultimately installed Rank Math by “Skipping the Step” of adding the Search Console during the install process. Seems to have been the best option to get Rank Math installed, at least mostly.

Once installed, I have gone back to the Rank Math > General Settings > Search Console to try to accomplish linking everything properly. I am able to successfully Authorize my “Search Console” account without issue. The site that I want to use as “My Search Console Profile” is then listed properly. I select it from the drop down menu. But then when selecting the “Save Changes” button at the bottom, I get sent to my site’s “This Page does Not seem to exist” page????

Further, when I go back to the Search Console Page within Rank Math, one of the other sites (other Search Console Profile) is shown as the selected site.

What am I doing wrong?

Thanks for your help.
