Accidentally deleted public folder in laravel

Hi I was working on a project in Laravel using Backpack for my admin panel and today I deleted my project's public folder accidentally.

Fortunately I had backup at my GitHub repository and I have copy pasted the public folder from there. But After pasting, now my project is running index.php at public but not using backpack's bootstrap and style sheets and other files. what I am doing wrong.

I am worried that I have lost my whole project. Please help to recover this problem. I have to submit my project tomorrow. Help please
