[Windows][26.924.2738.0] Persistent startup spinner — app_start timeout after auth/renderer ready; survives Repair and reinstall

Then include:

• Windows 11 build 26200
• ChatGPT Plus
• app version 26.924.2738.0
• worked before Sep 26 update
• config approval_policy not present
• Repair failed
• uninstall/reinstall failed
• normal/admin launch both fail
• codex doctor: 20 OK, 0 FAIL
• auth/WebSocket/network all healthy
• fresh log ends in name=app_start outcome=failure reason=timeout

What steps can reproduce the bug?

1. Install/update the official ChatGPT/Codex Windows app to version 26.924.2738.0.
2. Sign in with a ChatGPT Plus account.
3. Launch the Windows desktop app normally.
4. The main window opens as a blank/dark surface with a loading spinner.
5. Wait approximately 2 minutes.
6. The UI never becomes usable.
7. The desktop log records:
   name=app_start outcome=failure
   reason=timeout

The same result occurs after:

• Windows App Repair
• full uninstall/reinstall from Microsoft Store
• Windows reboot
• normal launch
• Run as administrator

The issue is reproducible on every launch.

No in-app session ID is available because the desktop composer never loads.
