I have to override Sender.php which path is MagentoSalesModelOrderEmail

I try but its not work my code is :

di.xml

<type name="MagentoSalesModelOrderEmailSender">
 <plugin name="module_name::aroundPrepareTemplate" type="modulenameModelOrderEmailSender" sortOrder="99999"/>
 </type>

modulenameModelOrderEmail
Sender.php

<?php 

 namespace modulenameModelOrderEmail;

 use MagentoSalesModelOrder;
 use MagentoSalesModelOrderEmailContainerIdentityInterface;
 use MagentoSalesModelOrderEmailContainerTemplate;
 use MagentoSalesModelOrderAddressRenderer;


 abstract class Sender
 

 protected $senderBuilderFactory;


 protected $templateContainer;


 protected $identityContainer;

 protected $logger;


 protected $addressRenderer;


 public function __construct(
 Template $templateContainer,
 IdentityInterface $identityContainer,
 MagentoSalesModelOrderEmailSenderBuilderFactory $senderBuilderFactory,
 PsrLogLoggerInterface $logger,
 Renderer $addressRenderer
 ) 
 $this->templateContainer = $templateContainer;
 $this->identityContainer = $identityContainer;
 $this->senderBuilderFactory = $senderBuilderFactory;
 $this->logger = $logger;
 $this->addressRenderer = $addressRenderer;
 


 public function aroundPrepareTemplate($subject,Order $order)
 
 $this->templateContainer->setTemplateOptions($this->getTemplateOptions());
 $objectManager = MagentoFrameworkAppObjectManager::getInstance();
 $orderItems = $order->getAllItems();

 foreach ($orderItems as $item) 

 $product = $objectManager->get('MagentoCatalogModelProduct')->load($item->getProductId());
 $categoryIds = $product->getCategoryIds();

 
 foreach($categoryIds as $catid)
 $_objectManager = MagentoFrameworkAppObjectManager::getInstance();
 $category = $_objectManager->create('MagentoCatalogModelCategory')
 ->load($catid);
 


 if ($order->getCustomerIsGuest()) 
 $templateId = $this->identityContainer->getGuestTemplateId();
 $customerName = $order->getBillingAddress()->getName();
 else 
 $templateId = $this->identityContainer->getTemplateId();
 $customerName = $order->getCustomerName();
 

 if($catid == 461) 
 $templateId = 11 ; 
 


 $this->identityContainer->setCustomerName($customerName);
 $this->identityContainer->setCustomerEmail($order->getCustomerEmail());
 $this->templateContainer->setTemplateId($templateId);
 


 

For your requirement, I am suggesting not use Plugin and it little complicated at this method and

Plugin doesn't work on PrepareTemplate as this Method is protected

Suggesting to use Class rewrite using <preference></preference>.

di.xml code

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
 <preference for="MagentoSalesModelOrderEmailSenderOrderSender" type="StackExchangeMagentoRewriteOrderSender" />
</config>

Rewrite class StackExchangeMagentoRewriteOrderSender.php

And code is below:

<?php
namespace StackExchangeMagentoRewrite;

use MagentoSalesModelOrder;
use MagentoFrameworkDataObject;

class OrderSender extends MagentoSalesModelOrderEmailSenderOrderSender

 /**
 * @var MagentoCatalogApiProductRepositoryInterface

 parent::__construct($templateContainer,
