Website quicklink buttons not working anymore

Our site has been up and working since 2020, the code we use for our quicklink buttons on the homepage just stopped working within the last few weeks. Our website can be viewed at www.gymagine.com. This is the code we have been using for 3 years, it has not been changed, but just stopped working:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script> 
   $(document).ready(function() { 
     $('.header-nav-folder-title[href="/classinfo1"]').attr("href", "/classinfo");
     window.addEventListener('load', function(){
       document.querySelector('[href="/classinfo"]').addEventListener('click', function() {
         window.location = "/classinfo";
       })
     })
   }); 
</script>
<script>
$(document).ready(function() { 
     $('.header-nav-folder-title[href="/about1"]').attr("href", "/about");
     window.addEventListener('load', function(){
       document.querySelector('[href="/about"]').addEventListener('click', function() {
         window.location = "/about";
       })
     })
   }); 
</script>
<script>
$(document).ready(function() { 
     $('.header-nav-folder-title[href="/team1"]').attr("href", "/team");
     window.addEventListener('load', function(){
       document.querySelector('[href="/team"]').addEventListener('click', function() {
         window.location = "/team";
       })
     })
   }); 
</script>
