Summary

Codex Windows Stable crashes on startup, while Codex Beta runs normally on the same Windows user profile.

Environment

• OS: Windows 10 Version 19043
• Codex Stable package: OpenAI.Codex_26.609.3341.0_x64__2p2nqsd0c76g0
• Codex.exe version: 149.0.7827.54

Behavior

When launching Codex Stable from the Windows Start menu or AppModel AppID, the app starts briefly and exits within a few seconds.

Codex Beta launches normally.

Reproduction Steps

1. Install Codex Stable from Microsoft Store.
2. Launch Codex Stable on Windows 10.
3. Codex.exe starts briefly.
4. Crashpad dump is created.
5. The app exits without showing the main window.

What was already ruled out

• AppModel activation succeeds.
• Appx package status is OK.
• Microsoft Store App Installer and winget are working.
• Codex user data was fully reset.
• Roaming profile at AppData\Roaming\Codex was reset.
• No AppLocker, CodeIntegrity, Defender, or Windows Error Reporting crash is generated.
• Previous DRM/security injected modules were removed or disabled.
• Crash dump loaded modules do not include Fasoo, Samsung SDS PC-DRM, Kings/KESS, SoftCamp, MarkAny, AhnLab, or nProtect.
• Mirage virtual display driver was removed.
• Codex Beta works normally.

Loaded modules include Codex.exe, chrome.dll, chrome_elf.dll, better_sqlite3, windows_updater, and Windows system DLLs.

Loaded modules do not include known DRM/security DLLs.

Expected Behavior

Codex Stable should launch normally, like Codex Beta does.

Actual Behavior

Codex Stable exits during Electron/Chromium/V8 initialization and creates a Crashpad dump.

Additional Note

I can provide the Crashpad dump privately if needed, but I am not attaching it publicly because it may contain local environment or user data.

What steps can reproduce the bug?

1. Install Codex Stable from the Microsoft Store.
2. Launch Codex Stable from the Start menu or with the AppModel AppID:

shell:AppsFolder\OpenAI.Codex_2p2nqsd0c76g0!App

1. The Codex.exe process starts briefly.
2. The app exits within a few seconds without showing the main window.
3. A Crashpad dump is created under:

C:\Users\이도현\AppData\Roaming\Codex\web\Codex\Crashpad\reports

1. Repeat the launch. The same crash behavior occurs again.

Codex Beta launches normally on the same Windows user profile.

What is the expected behavior?

Codex Stable should launch normally and show the main application window, the same way Codex Beta does on the same Windows user profile.

Additional information

I can provide the Crashpad dump privately if needed, but I am not attaching the raw .dmp file publicly because it may contain local environment or user data.

I have attached or can provide the WinDbg analysis text instead.

Important notes:

• Codex Beta works normally on the same Windows user profile.
• The Stable crash happens consistently.
• Previous DRM/security injected modules were removed or disabled.
• The latest Crashpad dump does not show Fasoo, Samsung SDS PC-DRM, Kings/KESS, SoftCamp, MarkAny, AhnLab, or nProtect modules.
• Mirage virtual display driver was removed, and AMD Radeon is now the only display adapter.
• The crash still occurs after resetting Codex user data and Roaming profile data.
