错误：在woocommerce中自动将待处理订单发送到已取消

The "hold stock (minutes)" functionality of woocommerce is not working properly with Woocommerce stock manager, disabling this plugin is not a possibility for us.

My intention is to send the pending orders to canceled after 5 minutes.

Here is my code attempt:

function wc_cancel_pending_orders() {
    if ( ! $order_id )
        return;

    $order = wc_get_order( $order_id );

    $prod_date = $order->order_date;
    $date_object = $order->order_date;
    $date_object->modify('+5 minutes ');
    $prod_is_new = (strtotime($prod_date) >= strtotime($date_object->format('Y-m-d')));

    if ($prod_is_new) {
        if( $order->has_status( 'pending' ) ) {
            $order->update_status( 'cancelled' );
        }
    } else {
        return;
    }
}
add_action( 'woocommerce_order_status_changed', 'wc_cancel_pending_orders' );

But it is not giving me results, any suggestions or corrections in this code?
