Windows: Statsig bootstrap fails on user.custom.workspace_type, disabling i18n and Browser Use

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

26.602.4764.0

What subscription do you have?

ChatGPT Plus

What platform is your computer?

Microsoft Windows NT 10.0.26200.0 x64

What issue are you seeing?

The Codex UI remains in English even though my Windows locale and Codex localeOverride are set to zh-CN. Browser Use and Chrome integration are also unavailable.

The logs repeatedly show:

Statsig: error while bootstrapping post-login client
user.custom.workspace_type: Invalid input

Browser availability shows:

available=false
reason=statsig-disabled

Repairing and restarting the Codex app did not resolve the issue.

What steps can reproduce the bug?

1. Launch Codex Desktop on Windows.
2. Sign in to my ChatGPT account.
3. Set the Windows system locale to zh-CN.
4. Set localeOverride = "zh-CN" in the Codex configuration.
5. Restart Codex.
6. Observe that the UI remains in English.
7. Check Browser Use or Chrome integration and observe that it is unavailable.
8. Repair the Codex app through Windows Settings and restart it.
9. The issue still occurs.

The logs show:

• user.custom.workspace_type: Invalid input
• browser_use_availability_resolved available=false reason=statsig-disabled

What is the expected behavior?

Codex should load the account feature configuration without a workspace_type validation error.

When the locale is set to zh-CN, the Codex interface should display in Simplified Chinese.

Browser Use and Chrome integration should be available when the account and subscription are eligible, rather than being disabled because the feature configuration failed to load.

Additional information

The browser plugin is installed and enabled in my Codex configuration.

My Windows system locale is zh-CN, and Codex renderer processes start with --lang=zh-CN. The locale configuration is therefore being detected, but the UI translation feature does not activate.

The Owl feature bootstrap cache remains empty:
{"enabledOwlFeatureNames":[]}

The same workspace_type validation error occurs after using the Windows “Repair” option and restarting Codex.

This may be an account feature-bootstrap data compatibility issue rather than a local installation problem.
