Windows Codex Desktop 26.608.1337 crashes immediately on launch and writes Crashpad dumps

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

The app does not stay open long enough to use the About dialog.

What issue are you seeing?

Codex Desktop on Windows does not open. Launching the app appears to start the process, but no usable window appears and the app exits/crashes almost immediately.

Concrete local evidence:

• The AppX package reports Status: Ok.
• Recent desktop log files are created for each launch attempt, but each log is only 328 bytes and stops immediately after startup.
• The latest desktop log contains only:

2026-06-10T05:19:27.632Z info Launching app agentRunId=null allowDebugMenu=false allowDevtools=false allowInspectElement=false buildFlavor=prod enableSparkle=false enableUpdater=true nodeEnv=undefined packaged=true platform=win32
2026-06-10T05:19:27.898Z info Appshot hotkey inactive configured=true enabled=true platform=win32

• At the same launch times, Crashpad dump files are written under the Codex package-local Crashpad reports directory. Three recent dumps were observed:

2026-06-10 14:18:04 KST, ~36.2 MB
2026-06-10 14:19:20 KST, ~36.2 MB
2026-06-10 14:19:28 KST, ~36.2 MB

• Windows Application event logs from the same period did not show matching Codex/Electron/crashpad errors.
• codex doctor --json reports overall warning, but auth, network reachability, WebSocket handshake, installation consistency, and state DB integrity are OK.
• One warning from codex doctor may or may not be related:

mcp.config: warning
node_repl: stdio command "C:\\Users\\<USER>\\AppData\\Local\\OpenAI\\Codex\\bin\\34ab3e1324cc55b5\\node_repl.exe" is not resolvable (path not found)

I am not uploading Crashpad dumps publicly because they may contain sensitive local memory/state, but they are available locally if the maintainers have a safe/private collection path.

What steps can reproduce the bug?

1. Install/update Codex Desktop for Windows to OpenAI.Codex_26.608.1337.0_x64__2p2nqsd0c76g0.
2. Launch Codex from the Windows Start menu/app entry.
3. Observe that no usable Codex window appears and the app exits/crashes immediately.
4. Check the Codex desktop logs and Crashpad reports directory.
5. Observe that the desktop log stops immediately after Launching app / Appshot hotkey inactive, and a new Crashpad dump is written for the launch attempt.

What is the expected behavior?

Codex Desktop should open normally and show the main window.

If startup fails, the app should show an actionable recovery/error message instead of silently exiting after writing only a minimal startup log.

Additional information

This blocks using Codex Desktop for work. The CLI is still present and codex doctor can run, but the Desktop app itself is not usable.

Because the crash happens before the app UI is usable, in-app /feedback cannot be used from the affected Desktop app session.
