Feedback ID: 01a11bdb-d9f3-7702-a3e0-96619372fd5d

What happened?

I set localeOverride = "zh-CN" in config.toml under [desktop] section.
After saving the config file, I fully quit Codex from tray menu and restart it.
But the UI is still English, cannot switch to Simplified Chinese.

Steps to reproduce:

1. Edit config.toml, add localeOverride = "zh-CN" under [desktop]
2. Save file
3. Quit Codex completely
4. Reopen Codex
5. Check UI language

Expected: UI becomes Simplified Chinese
Actual: UI remains English

What steps can reproduce the bug?

1. Open config.toml in folder C:\Users\Lenovo.codex\
2. Add localeOverride = "zh-CN" under [desktop] section
3. Save the file
4. Right-click Codex icon in system tray and choose Quit to fully exit
5. Launch Codex desktop app again
6. Check the UI language

What is the expected behavior?

After setting localeOverride = "zh-CN", the Codex desktop UI should show Simplified Chinese.
