### What version of the Codex App are you using (From “About Codex” dialog)? Codex Desktop App (installed from Microsoft Store) CLI version: 0.139.0 ### What subscription do you have? gpt plus ### What platform is your computer? Windows 11 x64 (Build 10.0.26200.8457) ### What issue are you seeing? Codex Desktop App does not launch on Windows 11. When I run: ```bash codex app ``` the following message is displayed: ```text Opening Codex Desktop workspace C:\Users\강민... ``` After that: * No GUI window appears * No taskbar icon appears * No error dialog appears * The application exits immediately Launching Codex Desktop App from the Windows Start Menu produces the same result. The CLI still works normally: ```bash codex --version ``` returns: ```text codex-cli 0.139.0 ``` and running: ```bash codex ``` opens the terminal interface successfully. Environment: * Windows 11 x64 (Build 10.0.26200.8457) * GPT Plus subscription * Codex CLI 0.139.0 * Installed from Microsoft Store * User profile path contains Korean characters: `C:\Users\강민` ### What steps can reproduce the bug? 1. Install and launch Codex Desktop App on Windows 11. 2. Open Command Prompt. 3. Run: ```bash codex app ``` 4. Observe the output: ```text Opening Codex Desktop workspace C:\Users\강민... ``` 5. No GUI window appears and the application exits immediately. Additional notes: * Rebooting Windows does not resolve the issue. * Reinstalling Codex Desktop App does not resolve the issue. * Removing ChatGPT Desktop App does not resolve the issue. * The issue persists after reinstalling Codex. * Codex CLI continues to work normally. ### What is the expected behavior? The Codex Desktop App should launch normally and display the GUI when I: * Launch Codex from the Windows Start Menu, or * Run `codex app` from Command Prompt The application should open the Desktop interface instead of exiting immediately. The behavior should be the same as before when the Desktop App was functioning normally. ### Additional information Additional observations: * The issue started shortly after installing the ChatGPT Desktop App. * I cannot confirm whether the two events are related, but the timing was very close. * Removing ChatGPT Desktop App did not resolve the issue. * Reinstalling Codex Desktop App did not resolve the issue. * Rebooting Windows did not resolve the issue. * Codex CLI continues to work normally. * The Desktop App previously worked correctly on this same machine. * My Windows user profile path contains Korean characters: ```text C:\Users\강민 ``` I am not sure whether this is relevant, but I wanted to mention it in case it affects Desktop App startup or workspace initialization.
