Magento 2.4.6-p3 – Creating an order programmatically causes errors when adding shipping address to quote

I am trying to create a free order with code, it all works up until adding a shipping address and method, it crashes with errors instead of creating the quote and i can’t see why as the code looks fine to me.

Billing address is no problem. I’m just going to provide a small section of the code relating to shipping address:

// add shipping address
            /** @var Address $shippingAddress */
            $shippingAddress = $this->_addressFactory->create();
            $shippingAddress->addData([
                'firstname' => (string)$order->Shipping->FirstName,
                'middlename' => (string)$order->Shipping->MiddleName,
                'lastname' => (string)$order->Shipping->LastName,
                'street' => [(string)$order->Shipping->Street],
                'city' => (string)$order->Shipping->City,
                'postcode' => (string)$order->Shipping->PostCode,
                'telephone' => (string)$order->Shipping->Telephone,
                'country_id' => (string)$order->Shipping->Country,
                'region' => (string)$order->Shipping->Region
            ]);

            $shippingAddress->setCollectShippingRates(true)
                ->collectShippingRates()
                ->setShippingMethod('freeshipping_freeshipping');

            $quote->setShippingAddress($shippingAddress);

            // add billing address
            /** @var Address $billingAddress */
            $billingAddress = $this->_addressFactory->create();
            $billingAddress->addData([
                'firstname' => (string)$order->Billing->FirstName,
                'middlename' => (string)$order->Billing->MiddleName,
                'lastname' => (string)$order->Billing->LastName,
                'street' => [(string)$order->Billing->Street],
                'city' => (string)$order->Billing->City,
                'postcode' => (string)$order->Billing->PostCode,
                'telephone' => (string)$order->Billing->Telephone,
                'country_id' => (string)$order->Billing->Country,
                'region' => (string)$order->Billing->Region
            ]);

            $quote->setBillingAddress($billingAddress);



             // collect all totals
             $quote->collectTotals();

             //$quote->getPayment()->setMethod('free');

            // save the quote
            $this->_cartRepo->save($quote);

this gives me an error:

Call to a member function getStoreId() on null#0
/vendor/magento/module-quote/Model/Quote/Address.php(1004):
MagentoQuoteModelQuoteAddress->requestShippingRates()

It seems to be this line in Address.php:

$storeId = $this->getQuote()->getStoreId() ?: $this->storeManager->getStore()->getId();
