v1.1.1: How to fix error not showing Tax on the checkout page when module enabled?

QUESTION: 

When we activate this extension it doesn't calculate the Tax in the cart or check out page.

We disable the extension and its Tax starts showing and works fine. 

Note that I use the latest version 1.1.1 and Magento 2.4.1.

Please provide us a guide to fix it?
