ChatGPT/Codex Windows app stuck on blank white screen with infinite spinner (26.924.2738.0) #49285
Description
Bonjour,
Je rencontre un problème de blocage au lancement de la nouvelle application ChatGPT/Codex pour Windows : l’UI reste entièrement blanche avec un cercle de chargement qui tourne indéfiniment.
Environnement
App version : 26.924.2738.0 (x64)
Package : OpenAI.Codex_2p2nqsd0c76g0
Windows : 10.0.26200.9550
Installation : Microsoft Store
Symptôme
Au démarrage : fenêtre blanche + spinner infini, même après plusieurs minutes
ChatGPT fonctionne normalement dans le navigateur avec le même compte
Les logs indiquent : app-server Codex démarre, connexion OK, authentification ChatGPT OK, runtime installé OK, mais l’interface ne se charge pas (suspect WebView/rendu UI)
Étapes de reproduction
Installer l’app depuis le Microsoft Store
Lancer l’application
Observer l’écran blanc + chargement infini
Résultat attendu
L’interface de l’application s’affiche et permet d’utiliser ChatGPT/Codex.
Résultat observé
UI blanche, aucune interaction possible.
Dépannage déjà tenté
Réparer et réinitialiser l’application Windows
Désinstaller / réinstaller (Microsoft Store)
Fermer tous les processus ChatGPT/Codex puis relancer
Tester un autre réseau + partage de connexion mobile
Tester sans accélération GPU
(Optionnel) Lancer en tant qu’administrateur / basculer l’agent en WSL : sans effet
Logs / pièces jointes
Je peux fournir : extraits de ~/.codex/sessions et ~/.codex/archived_sessions + captures d’écran (après suppression d’infos sensibles).
Merci.

English translation:
Hello,
I am experiencing a freeze when launching the new ChatGPT/Codex application for Windows: the UI remains completely white with a loading spinner that spins indefinitely.
Environment
App version : 26.924.2738.0 (x64)
Package : OpenAI.Codex_2p2nqsd0c76g0
Windows : 10.0.26200.9550
Installation : Microsoft Store
Symptom
At startup: white window + infinite spinner, even after several minutes
ChatGPT works normally in the browser with the same account
The logs indicate: Codex app-server starts, connection OK, ChatGPT authentication OK, runtime installation OK, but the interface does not load (suspected WebView/UI rendering issue)
Steps to reproduce
Install the app from the Microsoft Store
Launch the application
Observe the white screen + infinite loading
Expected result
The application interface appears and allows ChatGPT/Codex to be used.
Observed result
White UI, no interaction possible.
Troubleshooting already attempted
Repair and reset the Windows application
Uninstall / reinstall (Microsoft Store)
Close all ChatGPT/Codex processes, then relaunch
Try another network + mobile hotspot
Try without GPU acceleration
(Optional) Run as administrator / switch the agent to WSL: no effect
Logs / attachments
I can provide: excerpts from ~/.codex/sessions and ~/.codex/archived_sessions + screenshots (after removing sensitive information).
Thank you.

This issue has already been raised on September 26 on https://community.openai.com/t/windows-chatgpt-app-26-924-2738-0-stuck-on-blank-screen-endless-spinner/1400979 and has not been adressed by OpenAI yet. As a paying subscriber, I find it unadmissible that I cannot use the app as the CLI is not an adequate substitute for my workflow.

Additional diagnostic information:
I checked the Codex desktop logs. The app-server successfully starts and connects, ChatGPT authentication succeeds, and the primary runtime installs successfully.
Chromium Default/LOG and LOG.old are both empty (0 bytes).
The issue persists after fully terminating all ChatGPT processes and relaunching the app.
This seems to be a UI/renderer startup issue rather than an authentication, network, or app-server failure.
