Error CSS

This is the message that appears in the google Chorme console.

Also that css path no longer exists as I see in the content of the Plugin.

Refused to apply style from ‘https://www.politikaperu.org/wordpress/wp-content/plugins/kk-star-ratings/public/css/kk-star-ratings.css?ver=5.8.1’ because its MIME type (‘text/html’) is not a supported stylesheet MIME type, and strict MIME checking is enabled.
