I can't make it work on Xampp server

[Moxie5]

Hey, I'm using XAMPP server and I have simple htaccess to redirect to public folder. My router is not working correctly. If the uri is "/" it's working but when I type uri localhost/contact doesn't show the message or error and doesn't load. I got error from xampp server page not found. Even with out the htaccess file doesn't work. I also created virtual host but without results

Listen 81
<VirtualHost *:81>
DocumentRoot "F:\mvc\public"
<Directory "F:\mvc\public">
AllowOverride All
Require all granted

htaccess:

RewriteEngine On
RewriteBase /

RewriteCond %{THE_REQUEST} /public/([^\s?]*) [NC]
RewriteRule ^ %1 [L,NE,R=302]

RewriteRule ^((?!public/).*)$ public/$1 [L,NC]
