Invalid or non-working e-mail address when trying to save

I am trying to update the location of our meetings to a Zoom URL. When I make the change, or even if I make no changes, when I try to save, I get:

You have errors in your form below. Please scroll down and correct the following:
Administrator Info Tab - You have entered an invalid or non-working e-mail address. (No advertised SMTP servers are accepting mail.) One email address only please, in the form of name@address.com.

I can't find any email addresses in any of the tabs. Any suggestions appreciated. Thanks!

It is likely the administrator email address.

What is your club number without it we can only guess at the problem.
