I am receiving the same error, and apparently I cannot add to this without purchasing another license, which I should not have to on a regular basis.
Receiving this error on the front-end of the site after upgrading to 6.7 WP. A saw there are a couple of other people with the problem as well. Had debugging turned on by mistake and have since turned it off from displaying as well
Deprecated: Function wp_targeted_link_rel_callback is deprecated since version 6.7.0 with no alternative available. in /var/www/vhosts/asphaltspecialties.com/httpdocs/wp-includes/functions.php on line 6114
Probably not related to Enfold, but thought I would point it out.
It was a problem!
