Codex Desktop white screen after login - Statsig workspace_type Invalid input

Codex Desktop white screen after login

Summary

Codex Desktop opens to a blank white window after login. Login, network, app-server startup, and thread listing appear healthy, but the renderer logs a Statsig bootstrap error during post-login initialization.

Key Error

Statsig: error while bootstrapping post-login client
path: ["user","custom","workspace_type"]
message: "Invalid input"

Environment

macOS: 26.3.0 arm64
Codex App: 26.602.40724
Bundle version: 3593
Bundled CLI: codex-cli 0.137.0-alpha.4
Homebrew CLI: codex-cli 0.137.0
Auth: Logged in using ChatGPT

Diagnostics Already Tried

• Restarted Codex Desktop.
• Verified CLI auth: codex login status returns Logged in using ChatGPT.
• Ran codex doctor --summary; auth, websocket, reachability, config, and install are healthy.
• Cleared Chromium/GPU/code caches.
• Moved Local Storage and Session Storage.
• Moved full Electron profile:
• ~/Library/Application Support/Codex
• ~/Library/Application Support/com.openai.codex
• ~/Library/Caches/Codex
• ~/Library/Caches/com.openai.codex
• Reinstalled Codex Desktop via codex app /Users/bytedance.

The white screen still reproduces after full profile reset and app reinstall.

Relevant Healthy Startup Signals

window ready-to-show
window main frame finished load
account/read ... errorCode=null
thread/list ... errorCode=null
[startup][renderer] app routes mounted

Current Hypothesis

The issue appears to be a Codex Desktop renderer initialization failure caused by an account-side Statsig/custom user field value, specifically user.custom.workspace_type, not by local auth, local network, app installation, or stale profile cache.
