Not able to launch any Labs

I am not able to launch any labs in Ansible course. Its just blank screen

Labs - Modules - Packages - KodeKloud
Labs - Modules - Filecontent - KodeKloud

These are just 2 examples

It works fine , please check again now.

I am also not able to launch any Ansible labs course. The page looks not properly loaded and the buttons arent functional.
I have tried Mozzila Firefox, and MS Edge.
