What issue are you seeing?
VS Code Codex extension 26.721.30844 on Windows displays “Oops, an error has occurred” when opening local sessions.
The extension log reports:
403 Forbidden: /settings/user
attachAuth=false
Request ID: a203206cba13330d-KIN
The same extension-bundled Codex CLI successfully lists and resumes the sessions, confirming that the local session data is intact. Reloading the VS Code window did not resolve the extension UI failure.
What steps can reproduce the bug?
Just opening the extension
What is the expected behavior?
