Hi,
The Codex desktop app on Windows is showing the following error immediately after opening:
“Oops, an error occurred”
I have already tried:
- Closing all Codex, ChatGPT and OpenAI processes
- Uninstalling the application
- Removing the AppX package
- Deleting Codex/OpenAI folders from AppData and LocalAppData
- Renaming the .codex folder
- Restarting Windows
- Reinstalling the latest application version
- Clicking “Update ChatGPT” and “Try again”
The issue persists even after a clean installation.
Environment:
- Operating system: Windows 11 updated
- ChatGPT plan: Plus
- Country: Brazil
- Application: Codex / ChatGPT desktop app
- Error: “Oops, an error occurred”
The Codex CLI still works, but the desktop application does not.
Has anyone encountered this issue or found a fix?
I have also contacted OpenAI Support and attached a screenshot.
