Are you sure get_post_type_archive_link('activity') of type false|string can be used in concatenation?

It seems like $permalink can also be of type false; however, parameter $url of esc_url() does only seem to accept string, maybe add an additional type check?

52% of this comment could be valid code. Did you maybe forget this after debugging?
