haonas Hi
Somehow, there is a new class called monochrome
loaded on this page of your site which has filter so you did not see the modal popup.

I added custom css into this file of your site so the modal can work fine now: /media/templates/administrator/atum/css/user.css
body.admin.com_menus.view-item.layout-edit.task-display.monochrome.modal-open {
filter: none;
}
Kindly check.
