#7255 will fixes the infinite loop.
But I get another error:

No good. I can't get out of the dependency hell.

The Session depends on a Session driver. This is no problem.
The Session driver creation depends on a Request (AppServices::request()->getIPAddress()).
The IncomingRequest depends on Config\App!

Since IncomingRequest depends on Config\App::$supportedLocales, splitting Config\App does not solve this problem.

Using Session in Config\App is a misuse. This means using personalized values in Config.
But Config values should be the values for the system, not for a site visitor.
