Codex Desktop on Windows becomes unstartable after a second root is added

What happened
Another OpenAI Codex bug report says the Windows desktop app becomes unstartable after adding a second root path to an existing project. Restarting keeps landing on the same generic error screen until the broken project state is manually repaired.
Key findings
- The issue reproduces with two normal local folders on the same drive.
- The project JSON remains valid.
- Removing the second root from %USERPROFILE%\.codex\.codex-global-state.json and its backup restores normal startup.
- The reporter ruled out the project name as the cause; a special character in the name was not the problem.
Impact
The bug effectively bricks Codex Desktop until the saved multi-root state is edited.
