I focused merely on the solution and I just changed the function validateForCart
In vendor/magento/module-quote/Model/QuoteAddressValidator.php file :

from :

 public function validateForCart(CartInterface $cart, AddressInterface $address): void
    {
        $this->doValidate($address, $cart->getCustomerIsGuest() ? null : $cart->getCustomer()->getId());
    }

to :

public function validateForCart(CartInterface $cart, AddressInterface $address): void
    {
        $this->doValidate($address, $cart->getCustomerId() ? $cart->getCustomer()->getId() : null );
    }

It worked for me very well. Let me know if this trick helped you too.
