After upgrading from 2.2.5 to 2.2.6 or later I get this warning on pages with the MailChimp signup form in a block.

Warning: foreach() argument must be of type array|object, string given in Drupal\Core\Render\Element\Checkboxes::valueCallback()

It is related to the interest groups checkboxes. If I disable the option for users to select interest groups, the warning is gone.
