JQuery in Code Pen Stopped Working

I went back to my pomodoro clock i made a year or so ago on codepen and its no longer functioning. Any suggestions? https://codepen.io/MrGoldPWD/pen/oqERrd

Take a look at your browsers console first to see if you can figure out why you are getting some of those errors.

One thing I notice is you load two different versions of jQuery for some reason. Also, you need to make sure if any of the libraries are dependent on other libraries. For example, you may need to load jQuery before loading the nouislider library or even the bootstrap libraries.
