Redirect to "My Cart" and Incorrect Unavailability Message After Changing Address in Checkout

Describe the bug
Users of the Enatega Multivendor Customer App encounter a critical issue when attempting to change the address during the checkout process. Instead of updating the address seamlessly, the app redirects users to the "My Cart" section and displays an incorrect message indicating that one or more items are not available.

To Reproduce
Steps to reproduce the behavior:

Open the Enatega Multivendor Customer App.
Log in with valid credentials.
Add products to the cart and proceed to the checkout section.
Attempt to change the address during the checkout process.
Observe the redirection to the "My Cart" section and the incorrect unavailability message.
Expected behavior
When changing the address in the checkout section, the app should update the address without redirection to the "My Cart" section, and it should not display incorrect unavailability messages for items.
