Can't debug to fix virtual host issue on windows 10 - apache

Question

I have problem when i try to setup virtual host on my windows 10 pc.
In my hosts file:
127.0.0.1 project.dev
In my httpd-vhosts.conf
<VirtualHost *:80>
ServerAdmin webmaster#project.dev
DocumentRoot "path to project"
ServerName project.dev
ErrorLog "logs/project.dev-error.log"
CustomLog "logs/project.dev-error-access.log" common
<Directory path to project>
Require all granted
Allowoverride All
</Directory>
</VirtualHost>
httpd.exe run without error.
I try to run:
localhost
It works but when i try to run:
project.dev
in the browser, it does not work.
This site can’t be reached
project.dev refused to connect.
Try:
Checking the connection
Checking the proxy and the firewall
ERR_CONNECTION_REFUSED
I have tried to solve this issue for hours but i can't.
Windows firewall logs, System logs, Applications logs, Apache logs don't show me any infos to help me.
Could anyone help me debug this issue?
Thanks!
------------UPDATE--------
Today, i updated php and apache to newer version
https://windows.php.net/downloads/releases/php-7.2.6-Win32-VC15-x64.zip
https://www.apachehaus.com/downloads/httpd-2.4.33-o110h-x64-vc14-r2.zip
and tried to run project.dev with simple vhost:
<VirtualHost *:80>
DocumentRoot "C:/Users/0x1111/workspace"
ServerName project.dev
#ServerName www.example.com:80
</VirtualHost>
Chrome shows https error:
Your connection is not private
Attackers might be trying to steal your information from project.dev (for example, passwords, messages, or credit cards). Learn more
NET::ERR_CERT_AUTHORITY_INVALID
Running localhost it works normal.
----UPDATE -----
when i use nslookup localhost:
Server: resolver1-fs.opendns.com
Address: 208.67.222.123
Non-authoritative answer:
Name: localhost
Addresses: ::1
127.0.0.1
But when i nslookup project.dev:
Server: resolver1-fs.opendns.com
Address: 208.67.222.123
*** resolver1-fs.opendns.com can't find project.dev: Non-existent domain
