Describe the bug
Double initializing of the config class. Problem is that I am extending config class Filters from module. I have setup that I have shared configs between all apps and I am extending main config file located in shared folder by apps config. But happens that auto discovery is trying to make second initializing run in my shared folder a that makes fatal error for initializing already initialized class.

CodeIgniter 4 version
4.0.4 (develop)

Affected module(s)
Config

Expected behavior, and steps to reproduce if appropriate
Auto discovery should no try initialize already initialized class. There should be check to prevent it.
