[Bug] Windows Desktop App (26.422.3464.0) white screen on startup due to workspace_dependencies loop

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

26.422.3464.0

What subscription do you have?

ChatGPT Plus

What platform is your computer?

Windows 11 x64

What issue are you seeing?

App opens to a blank white window with the Codex >_ icon/spinner.
Multiple Codex.exe processes remain in the background after closing the window.

Checking the logs, the app is stuck in a loop trying to enable a feature that the runtime does not support:

unsupported feature enablement 'workspace_dependencies': currently supported features are apps, memories, plugins, tool_search, tool_suggest, tool_call_mcp_elicitation
method=experimentalFeature/enablement/set
Failed to sync experimental feature enablement

What steps can reproduce the bug?

1. Install the Codex App from the Microsoft Store.
2. Launch the application.
3. Observe the app getting stuck indefinitely on the initial loading screen (white screen with the cloud logo).

What is the expected behavior?

The app should finish loading and display the main chat/workspace interface successfully.

Additional information

Resetting the app via Windows Settings, reinstalling from the Store, and clearing the AppData/User data did not fix the issue.
It appears to be an internal frontend-backend feature flag mismatch (workspace_dependencies) in this specific Windows build.
