Nginx - PHP never render. Html files work well

when I enter PHP files, they load forever. But do not show up in the browser. After few minutes the browser goes to timeout.

Html files get shown/rendered correctly.

Here is my virtualhost:

server {
    listen 80;
    
        server_name localhost;

    root /var/www/site;
    index index.php index.html;

    location / {
        try_files $uri $uri/ /index.php?$args;
    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
    }
}

And here are the most important things in the www.conf:

listen = /var/run/php/php7.2-fpm.sock
user = www-data
group = www-data

In php.ini I have:

cgi.fix_pathinfo=0

Of course I restarted php and nginx. I have no idea what's the problem

Versions:

nginx version: nginx/1.18.0 (Ubuntu)
PHP 7.2.34-36+ubuntu20.04.1+deb.sury.org+1 (cli) (built: Oct 28 2022 18:25:54) ( NTS )

Can anyone please help?
