The woocommerce_checkout_update_order_review hook, is an action hook with a unique argument. As it's an action hook, nothing is need to be returned as the filter hooks does.

Try this revisited code version, tested without any thrown errors:

add_action( 'woocommerce_checkout_update_order_review', 'action_woocommerce_checkout_update_order_review', 10, 1 );
function action_woocommerce_checkout_update_order_review( $posted_data ) {
    WC()->cart->calculate_shipping();
}
