Magento 2 Add product to product collection

Question

currently i'm working on an extension which show the last products which sold the last 10 day. I got this products with the \Magento\Reports\Model\ResourceModel\Product\Sold\Collection.

Vender/Name/etc/di.xml:

<type name="Magento\Catalog\Model\Layer">
    <plugin name="vendor_add_last_sold_products" type="Vendor\Name\Plugin\Layer" />
</type>

Vender/Name/Plugin/Layer.php:

namespace Vendor\Name\Plugin;

use Magento\Catalog\Model\ResourceModel\Product\Collection;
use Magento\Catalog\Model\ResourceModel\Product\CollectionFactory;
use Magento\Catalog\Model\Product;
use Magento\Framework\Registry;
use \Vendor\Name\Helper\Orders;

class Layer
{
    protected $_orders;

    protected $_product;

    protected $_registry;

    public function __construct(
        Orders $orders,
        Product $product,
        Registry $registry
    )
    {
        $this->_orders = $orders;
        $this->_product = $product;
        $this->_registry = $registry;
    }

    public function aroundGetProductCollection(\Magento\Catalog\Model\Layer $subject,\Closure $proceed) {

        $collection = $proceed();
        $category = $this->_registry->registry('current_category')->getId();
        $sold_products = $this->_orders->getLastSoldProducts($category);

        if($sold_products) {
            foreach($sold_products as $product) {
                if (!array_key_exists((int)$product->getId(), $collection->getItems())) {
                    $collection->addItem($this->_product->load((int)$product->getId()));
                }
            }
        }

        return $collection;
    }
}

In $sold_products i saved all sold products. And with:

if($sold_products) {
   foreach($sold_products as $product) {
      if (!array_key_exists((int)$product->getId(), $collection->getItems())) {
         $collection->addItem($this->_product->load((int)$product->getId()));
      }
}

I loop through all sold products and add them to the product collection. But i get always the following error:

Anyone has an idea/solution?

In my case that's happen because in modules I have some module files which overrided from 3rd party modules. I disable it and everything works good. If you need that module in your project you can use this

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <!-- setup_version is not a module version -->
    <module name="Test_Main" setup_version="2.15.4">
        <sequence>
            <!-- moduls -->
            <module name="Test_1"/>
            <module name="Test_2"/>
            <!-- moduls -->
        </sequence>
    </module>
</config>

in module.xml
