Laravel Dusk - Class config does not exist

The issue is with .env file App_Name

in the original file its written this way>>> APP_NAME=Application Name

Make it like this APP_NAME="Application Name"

I had this error in the log

Class config does not exist

the problem with me was that in the .env file I had set a configuration variable in the following way:

APP_NAME=Application Name

note the space. When I changed it to this:

APP_NAME="Application Name" 

the problem got fixed
