Codeigniter 4 Debugging

I used to use CI3 then moved over to Laravel. I am keen to start my new game project using CI4, but am battling to get around some of issues.

The main issue that I am having is the debugging mode in development.

Code:

#--------------------------------------------------------------------
# ENVIRONMENT
#--------------------------------------------------------------------

# CI_ENVIRONMENT = development

#--------------------------------------------------------------------
# APP
#--------------------------------------------------------------------

# app.baseURL = 'http://localhost/simplife/'
# If you have trouble with `.`, you could also use `_`.
# app_baseURL = ''
# app.forceGlobalSecureRequests = false
# app.CSPEnabled = false

#--------------------------------------------------------------------
# DATABASE
#--------------------------------------------------------------------

# database.default.hostname = localhost
# database.default.database = ci4
# database.default.username = root
# database.default.password = root
# database.default.DBDriver = MySQLi
# database.default.DBPrefix =
# database.default.port = 3306

# database.tests.hostname = localhost
# database.tests.database = ci4_test
# database.tests.username = root
# database.tests.password = root
# database.tests.DBDriver = MySQLi
# database.tests.DBPrefix =
# database.tests.port = 3306

I have set the CI_ENVIRONMENT = development and I have set the base URL.

When there is an issue on the page, I get no details of the issue, simply a message stating Whoops.

I have tried the app on Laragon, Xampp and now on Wampserver. I get no details of errors at all. Please help
