Environnement problems with two laravel project on same server

I had a mistake and I would like to know why it appeared. I have two laravel projects on the same Apache2 ubuntu server. Both projects have two different mysql databases that can be used with phpmyadmin.

When I created my second laravel project (very distinct), I initialized all my environment variables correctly (it worked well). But on my first project, the "login" route returned an error saying that the "auth.login" view did not exist and debugged the session environment variables of my second project (connection information, etc...)

Do you know how this is possible?
