What to do if the name of the folder with the project disappears from the url, and the browser displays "Object not found!"?

Question

xampp

OS linux mint, installed xampp, uploaded test folder with wordpres template from composer https://github.com/wpscholar/wp-skeleton to htdocs . Entering the url " localhost/test " returns the url " localhost/wp/wp-admin/install.php ". But when you enter " localhost / test / wp / wp-admin / install.php " everything works, because it should be so, but it's always impossible to enter manually, and it's inconvenient. With wp-login the same situation. For some reason, the name of the folder disappears when prompted. And if you throw the project directly into htdocs, then everything works. /opt/lampp/htdocs - works, /opt/lampp/htdocs/test no longer works. Cleared cache, changed document root. I changed vhosts to the test folder, but it still points to the root of the folder. Help me please.
