Magento 2: Can't Override Magento\Quote\Model\Cart\ShippingMethodManagement - overriding

Question

I am trying to override Magento\Quote\Model\Cart\ShippingMethodManagement to intercept a bug with shipping address thrown in the apply function.
My app/code/vendor/module/etc/frontend/di.xml is this:
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/ObjectManager/etc/config.xsd">
<preference for="Magento\Quote\Model\ShippingMethodMangement" type="Vendor\Module\Model\Rewrite\ShippingMethodMangement" />
</config>
and app/code/Vendor/Model/Rewrite/ShippingMethodManagement.php
<?php
namespace Vendor\Module\Model\Rewrite;
use Magento\Customer\Api\Data\AddressInterfaceFactory;
use Magento\Framework\App\ObjectManager;
use Magento\Framework\Exception\CouldNotSaveException;
use Magento\Framework\Exception\InputException;
use Magento\Framework\Exception\NoSuchEntityException;
use Magento\Framework\Exception\StateException;
use Magento\Framework\Reflection\DataObjectProcessor;
use Magento\Quote\Api\Data\AddressInterface;
use Magento\Quote\Api\Data\EstimateAddressInterface;
use Magento\Quote\Api\ShipmentEstimationInterface;
use Magento\Quote\Model\ResourceModel\Quote\Address as QuoteAddressResource;
/**

*/
class ShippingMethodManagement extends \Magento\Quote\Model\ShippingMethodManagement implements
\Magento\Quote\Api\ShippingMethodManagementInterface,
\Magento\Quote\Model\ShippingMethodManagementInterface,
ShipmentEstimationInterface
{

public function __construct(
\Magento\Quote\Api\CartRepositoryInterface $quoteRepository,
\Magento\Quote\Model\Cart\ShippingMethodConverter $converter,
\Magento\Customer\Api\AddressRepositoryInterface $addressRepository,
\Magento\Quote\Model\Quote\TotalsCollector $totalsCollector,
AddressInterfaceFactory $addressFactory = null,
QuoteAddressResource $quoteAddressResource = null
) {
$this->quoteRepository = $quoteRepository;
$this->converter = $converter;
$this->addressRepository = $addressRepository;
$this->totalsCollector = $totalsCollector;
$this->addressFactory = $addressFactory ?: ObjectManager::getInstance()
->get(AddressInterfaceFactory::class);
$this->quoteAddressResource = $quoteAddressResource ?: ObjectManager::getInstance()
->get(QuoteAddressResource::class);
}
/**
* {#inheritDoc}
*/
public function apply($cartId, $carrierCode, $methodCode)
{
/** #var \Magento\Quote\Model\Quote $quote */
$quote = $this->quoteRepository->getActive($cartId);
if (0 == $quote->getItemsCount()) {
throw new InputException(
__('The shipping method can\'t be set for an empty cart. Add an item to cart and try again.')
);
}
if ($quote->isVirtual()) {
throw new NoSuchEntityException(
__('The Cart includes virtual product(s) only, so a shipping address is not used.')
);
}
$shippingAddress = $quote->getShippingAddress();
if (!$shippingAddress->getCountryId()) {
// Remove empty quote address
$this->quoteAddressResource->delete($shippingAddress);
throw new StateException(__('*** The shipping address is missing. Set the address and try again.'));
}
$shippingAddress->setShippingMethod($carrierCode . '_' . $methodCode);
}
}
I have run rm -r var/generated, s:up, s:d:c, c:f, s:s:d
No errors are thrown on compile but the model override doesn't work. The apply method is not hit in this file and is still run from Magento\Quote\Model\ShippingMethodManagement
Can anyone explain why this override isn't working?

Try placing the di.xml in the following path:
app/code/Vendor/Module/etc/di.xml
<?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="Magento\Quote\Model\ShippingMethodMangement" type="Vendor\Module\Model\Rewrite\ShippingMethodMangement" />
</config>
