File .env not working

Hello; thanks for yout help!
the name is correct (.env)
I update the proyect:
λ composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)
Package operations: 0 installs, 1 update, 0 removals
- Updating sebastian/environment (4.2.2 => 4.2.3): Downloading (100%)
Writing lock file
Generating autoload files
Generated autoload files containing 625 classes

and still not working

I try to uncomment (I remove the #) I set up an environment and it doesn't take it, I misconfigured the database and it doesn't take it
It simply does not recognize the file .env

Do i have some additional configuration to take the .env file?
