Why is the browser loading files incorrectly?

Question

JavaScript

When debugging the site, javascript stopped working. In the developer tools, on the sources tab in the index.js file, the html of the index.html file is displayed. At the same time, the jQuery files are loaded. The paths are written correctly, in the index.js javascript.
