That’s seem have special mixed shortcode in onepage and it cause the issue.
We still can’t login to your site with old error but you can try to fix it by go to:
wp-content/themes/haru-circle/assets/js/ then open file haru-circle.js
Go to line 1381 and change the code from:
var element = '.film-item'; // .item
var element = '.film-shortcode-wrapper .film-list .film-item'; // .item
Hope this helps!
