project name getting removed from the link in laravel

I have a laravel project running in my Win10 laptop using xampp,I was trying to remove the /public from the address bar but I ended up making my project unrunnable,I removed all the changes which I have done and brought it back to how it was. Now,when I run localhost/myprojectname/public it shows me this
