The site test.loc cannot process this request yet. HTTP ERROR 500. What to do?

Question

Apache HTTP Server

Good afternoon. I cloned the repository, I want to open it using a virtual host, I seem to have set everything up, but when I enter the test.loc address in the browser, the page displays such an error. How to fix it? Or maybe I configured the host incorrectly?

This error code literally means "something went wrong".
Exactly what needs to be figured out. It could be anything.
