[Ajax] browser console synchronous error using .load()

[Ajax] browser console synchronous error using .load()

Hello community,

I'm new to jquery with some bases and I need your help to solve my problem that takes me a lot of time
Basically, I want a dynamic page where I can load any page on click (I have 2 pages). In practice, all in working fine, up to a certain limit... When I trigger the click one time, I get errors, and with multiple trigger click its even worse and ends with a browser freeze.

Index.html :
  1. <p class="click-see" href="inc/print.html">Enter</p> // When I click for example here
  2.  <section id="dynamic"></section> // Load its href in this section
Here is the loaded page inc/print.html which contain the back button :
as you can see I had to link affected scripts to make them work
  1. <!DOCTYPE html>
    <html>
    <head>
        <meta charset="utf-8" />
        <title></title>
    </head>
    <body>

              <div id="dynamic-print"></div>
              <div id="box">
                  <h4 class="box-title"> Content </h4>
              </div>
              <div class="click-return">Back</div>

        <script type="text/javascript" src="js/jquery-3.2.1.min.js"></script>
        <script type="text/javascript" src="js/pageload.js"></script>
    </body>
    </html>

Jquery code :
(with an animation to scroll directly to the loaded content)

  1. $(document).ready(function() {

        $('.click-see').click(function() {
          
            $("#dynamic").load($(this).attr('href'));     // Enter button
            $('html, body').animate({
                scrollTop: $('#dynamic').offset().top
            }, 750);
        });

        $('.click-return').click(function() {            // Back button
             
            $('html, body').stop().animate({
                scrollTop: 0
            }, 500, 'swing');
            setTimeout(
                function() {
                    $("#dynamic").empty($(this).attr('href'));
                }, 500);
        });
    });
And errors obtained :
for example I clicked this way :
1 time on "Enter", 1 time on "Back" (x2) and errors occur only when I click on "Enter"

Definitely there is something I'm missing or doing wrong. I hope you can provide me some light about this

Regards
