Windows Codex App stuck on splash screen after Store reinstall/register; logs show ready-to-show

What version of the Codex App are you using (From “About Codex” dialog)?

Codex Windows Store app package: OpenAI.Codex_26.616.6631.0_x64__2p2nqsd0c76g0 App-server version in log: 0.142.0-alpha.6 I cannot access “About Codex” because the app is stuck on the splash screen.

What issue are you seeing?

Codex Windows desktop app remains visually stuck on the splash / renderer initialization screen.

The app does not crash. Processes stay alive and report Responding=True. Desktop logs show that
the app-server transport starts, the initialize handshake succeeds, the main frame finishes
loading, and the window reaches ready-to-show, but the visible window remains on the splash
screen.

This started after Codex was reinstalled/repaired by Microsoft Store/AppX on 2026-06-22. The app
worked a few days earlier.

What steps can reproduce the bug?

1. Launch Codex from the Windows Start menu / Microsoft Store app entry.
2. Wait for initialization.
3. The window remains stuck on the splash / renderer initialization screen.

I tried:

• Closing all Microsoft Store Codex desktop processes.
• Renaming GPU/cache directories under the Electron/Chromium profile.
• Renaming the full web profile so Codex rebuilt a fresh profile

After rebuilding the profile, the same issue remains.

What is the expected behavior?

Codex should leave the splash screen and show the main app UI or sign-in screen.
