Having trouble getting the Bootstrap navbar mega menu to function properly on an Asp.Net Core platform

I attempted to incorporate a Bootstrap navbar mega menu dropdown into my layout using the code from this source:

However, after downloading and inserting the code into my layout, the mega menu does not expand or take any action when clicked. In the Chrome inspect section, aria-expanded always remains as aria-expanded="false". What could I be missing?

_Layout.cshtml

<!DOCTYPE html>
<html lang="en">
... (Omitted for brevity) ...
</html>
<script type="text/javascript">
    /// some script

    // jquery ready start
    $(document).ready(function () {
        // jQuery code

        //////////////////////// Prevent closing from click inside dropdown
        $(document).on('click', '.dropdown-menu', function (e) {
            e.stopPropagation();
        });


    }); // jquery end
</script>

If you are looking to optimize your website's performance, consider removing the following code snippet from the <head></head> section:

 <!-- jQuery -->
    <script src="https://code.jquery.com/jquery-2.2.4.min.js" integrity="sha256-BbhdlvQf/xTY9gja0Dq3HiwQF8LaCRTXxZKRutelT44="
            crossorigin="anonymous"></script>

    <!-- Bootstrap files (jQuery first, then Popper.js, then Bootstrap JS) -->
    <link href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" rel="stylesheet" type="text/css" />
    <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/js/bootstrap.bundle.min.js" type="text/javascript"></script>
