Uncaught TypeError: e.indexOf is not a function while upgrading JQuery version

I got an error while upgrading jQuery version from 2.2.4 to 3.6.3 and Bootstrap from 3.3.6 to 3.3.7.

enter image description here

HTML CODE:

<!--                </script>-->
            <script src="/static/vendors/jsencrypt/jsencrypt.min.js"></script>
        {% endblock js %}
    {% endblock body %}
</body>

When web page is loaded , it is taking too much time . Can anyone suggest a solution to solve this issue?
