Magento 2 A customer with the same email already exists in an associated website error

Question

I'm stuck in a weird problem.

Everytime I try to create an account and add an address to that account programmatically I get an error called

A customer with the same email already exists in an associated website

This is my code for adding shipping and billing address to customer.

$customer->save();
        $customer->sendNewAccountEmail();
        //$customerId = $customer->getId();
        //Address info

         $customerAddress = $this->customerFactory->create()->setWebsiteId($websiteId)->loadByEmail($customer_email);
         $customerId = $customerAddress->getId();


         $address = $this->addressDataFactory->create();
         $address->setFirstname($parameters["first-name"])
            ->setLastname($parameters["last-name"])
            ->setCountryId("US")
            //->setRegionId("1")
            //->setRegion("")
            ->setCity('n/a')
            ->setPostcode($parameters["zip"])
            ->setCompany('n/a')
            ->setCustomerId($customerId)
            ->setStreet(['n/a'])
            ->setTelephone($parameters["phone"])
            >setIsDefaultBilling(1)
            ->setIsDefaultShipping(1);

        $this->addressRepository->save($address);

Of course I'm adding differnt emails everytime I run this controller, but for some reason it keeps telling me that the email is already associated with another customer.

Please help

First you have to check customer in website exist or not ?

 public function __construct(\Magento\Customer\Api\AccountManagementInterface $customerAccountManagement,
\Magento\Customer\Model\CustomerExtractor $customerExtractor
    )
    {
        $this->customerAccountManagement = $customerAccountManagement;
        $this->customerExtractor = $customerExtractor;
    }

        public function execute()
        {
            $customerEmail = 'customer email address';
            $websiteId = (int)$this->storeManager->getWebsite()->getId();
            $isEmailNotExists = $this->customerAccountManagement->isEmailAvailable($customerEmail, $websiteId);
        
            if ($isEmailNotExists == '1') {
                $customerData = ['set your customer Data];
                $request = $this->requestFactory->create();
                $request->setParams($customerData);
                $customer = $this->customerExtractor->extract('customer_account_create', $request);
                $password = $this->generatePassword();
                $customer = $this->customerAccountManagement->createAccount($customer, $password);
                $this->_customerSession->setCustomerDataAsLoggedIn($customer);
            } else {
                $customer = $this->_customer;
                $customer->setWebsiteId($websiteId);
                $customer->loadByEmail($customerEmail);
                $this->_customerSession->setCustomerAsLoggedIn($customer);
            }
        }
        
        
        public function generatePassword()
        {
            $characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
            $randomString = substr(str_shuffle($characters), 0, 10);
            return $randomString;
        }

Once your forgot this line we got same error.

$customer = $this->accountManagement
                ->createAccount($customer, $password, $redirectUrl);
