Are you using an ACF email field for the email field or a text field?

ACF already validates for a valid email address.

If you are using an email field, just for giggles, try changing the priority of your validation filter to something > 10

add_filter( 'acf/validate_value/key=field_644ad72c57f66', 'validate_email_field', 20, 4 );
