Links breaking after Netlify deployment

Question

After deploying to netlify, my links suddenly break with a 404 error message. When going over my code I see that the click events have a line through them. This is my first time using jQuery, any ideas?

$('.projects-index').click(function () {
    zoomIn();
    setTimeout(() => {
      location.href = '_projects.html';
    }, 500);
  });

This is the link to my site, https://portfolio-neelam-khan.netlify.app/
