Symfony version(s) affected

6.4.2

Description

after migrating a Symfony project from 6.3.* to 6.4.2 I discovered that the function getenv always return false instead of the value in the file .env
also, I was able to have the same behavior with a new project (Symfony 6.4.2)

How to reproduce

Create a new project Symfony 6.4.2
create a function in a controller that call dd(getenv('APP_ENV')); for example
Observe the results (screenshot)
