CodePudding user response：

You're mixing HTML Markup for Bootstrap 5 and importing Bootstrap 4.1.3. One of the key differences is:

Bootstrap 5 (As per your code): <button type="button" data-bs-toggle="collapse" data-bs-target="#navLinks">

Bootstrap 4: <button type="button" data-toggle="collapse" data-target="#navLinks">

Two options:

Change your HTML to the HTML markup for a navbar as per https://getbootstrap.com/docs/4.1/components/navbar/
Change your bootstrap imports to Bootstrap 5 (preferred):

<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-EVSTQN3/azprG1Anm3QDgpJLIm9Nao0Yz1ztcQTwFspd3yD65VohhpuuCOmLASjC" crossorigin="anonymous">

Have you included the css link? You may also modify the top javascript bootstrap link by doing something like this.
