Heroku - Clone Laravel

I just have this problem today when I switched back to Windows 8.1 from Ubuntu 16.04.

So I was working this morning on Ubuntu and switched back to Windows for PS stuff. Once I finished, I opened my local repo for some modifications thru GitKraken but it won't stop loading the repo anymore - it's stuck up to the loading screen. So I went to terminal to check via git log and no logs anymore! As if it was a knew repository at all. To confirm that, I opened my Atom editor and all files are green :( - meaning they're not git'd yet.

Fortunately, yesterday, I pushed my work to Heroku. I just lost some hours because right after I pushed, I added more work especially on the CSS.

So I thought I should just clone my work from Heroku

heroku git:clone -a my-app

Then I opened my Laravel server php artisan serve (no errors printed)

The errors says something related to vendors. So I issued composer update

But when I checked to browser for the home page it says "Whoops! Looks like something went wrong"

At this point I have no idea what to do. Any clues?
