It could be that ACF does not know where to get the field from. the body tag hook happens outside of the loop.

function add_acf_body_class($class) {
    $queried_object_id = get_queried_object_id();
    $value = get_field('page_layout', $queried_object_id);
    $class[] = $value;
    return $class;
}
add_filter('body_class', 'add_acf_body_class');
