"Not Found" route - Ubuntu 18, Apache, Laravel

I have moved my site from Windows to Ubuntu. Now, I am using Ubuntu with Apache. I can access the root of the site, but all routes are with 404 error.

This is /etc/apache2/apache2.conf:

<Directory /var/www/project_folder/public>
    Options Indexes FollowSymLinks
    AllowOverride All
    Require all granted
</Directory>

This is site config file:

    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/project_folder/public
    ServerAlias www.url here
    ServerName url here

And this is .htaccess:

AddType text/css .css
<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews -Indexes
    </IfModule>

    RewriteEngine On

    # Handle Authorization Header
    RewriteCond %{HTTP:Authorization} .
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

    # Redirect Trailing Slashes If Not A Folder...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_URI} (.+)/$
    #RewriteRule ^ %1 [L,R=301]
    RewriteRule ^(.*)/$ /$1 [L,R=301]

    # Handle Front Controller...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]
</IfModule>
