Last update broke our Church Admin?

Our system just updated to Version 2.72480 and we are now receiving a banner on all admin pages (not on the front end) saying “cron emails settings have changed” and nothing we do will remove it and we can’t get past it to work with any plugin or other WordPress function. I manually disabled all plugins and then enabled them one by one and it was gone and the system worked normally until I got to the Church Admin Plugin and then the error/banner came back.

All other plugins are up to date and WordPress is version 5.6.2 All running on our own Windows 2012R2 inhouse Server

If there’s not a quick fix is there an easy way of rolling back this version so that things return to a more normal state?

Thanks.
