oc-admin Error 500, fresh install

Dear community, I have newly installed osclass, with PHP 7.4-fpm and Nginx reverse proxy, but when I try to access /oc-admin page I get 500. I look that file omega_login.php is missing, I didn't find it in explorer as root.

In the Nginx error log:

[error] 6722#6722: *26595 FastCGI sent in stderr: "PHP message: PHP Warning: require(/www/osclass/oc-admin/gui/omega_login.php): failed to open stream: No such file or directory in /www/osclass/oc-admin/login.php on line 213 PHP message: PHP Fatal error: require(): Failed opening required '/www/osclass/oc-admin/gui/omega_login.php'
(include_path='/www/osclass/oc-includes/htmlpurifier:.:/usr/share/php') in /www/osclass/oc-admin/login.php on line 213" while reading response header from upstream, client: <myIP>, server: portal.mydomain.com, request: "GET /oc-admin/index.php?page=login HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/php7.4-fpm.sock:", host: "portal.mydomain.com"

Thanks a lot!
