Cause

This issue is the same as #6047, which the maintainer consolidated for follow-up. The reporter used Windows, Codex from the Microsoft Store, and Hermes installed on the D drive. The issue did not specify why detection failed or provide further troubleshooting results. The maintainer said version 4.0 substantially changed configuration switching and the interface, and many related issues no longer occur.

Fix
