The MageWorx_ShippingRules module retrieves country information from Magento in an incorrect way:

github.com

keyclampstore-com/m/blob/2026-02-02/vendor/mageworx/module-shippingrules/Block/Cart/LayoutProcessor.php#L122-L124


      
          $currentCountry = $shippingAddress
              ->getCountryModel()
              ->loadByCode($customerData->getCode());

To solve the problem, I replaced the incorrect MageWorx_ShippingRules code with a call to the df_country() function from my mage2pro/core library:

github.com

keyclampstore-com/m/blob/2026-02-02-2/vendor/mageworx/module-shippingrules/Block/Cart/LayoutProcessor.php#L122-L128

          			$currentCountry = df_country($customerData->getCode(), false);
