Codex Windows Desktop crashes immediately after startup on Windows 10.0.26200

## Summary

Codex Desktop for Windows launches, writes the first startup
log lines, then exits immediately. A Crashpad .dmp is
created on every launch. The CLI continues to work.

## Environment

• Codex Windows app: 26.611.8604.0
• Previous version before reinstall/update: 26.611.8273.0
• Codex CLI: 0.140.0
• Windows: 10.0.26200
• Runtime shown in Sentry scope: Electron/Chrome

149.0.7827.115

• CPU: 11th Gen Intel Core i5-1135G7
• GPU: Intel Iris Xe Graphics
• GPU driver: 32.0.101.6874
• Timezone: Asia/Singapore

## Repro Steps

1. Install Codex Desktop from Microsoft Store / `winget

install Codex -s msstore`.

1. Launch Codex Desktop normally or via:

```powershell
codex app "C:\Users\전목련\Vibe coding\organizer"

1. App exits before showing a usable window.

## Observed Behavior

Latest app log contains only:

Launching app agentRunId=null allowDebugMenu=false
allowDevtools=false allowInspectElement=false
buildFlavor=prod enableSparkle=false enableUpdater=true
nodeEnv=undefined packaged=true platform=win32
Appshot hotkey inactive configured=true enabled=true
platform=win32

A new Crashpad dump is created for each launch.

## Expected Behavior

Codex Desktop should stay open and show the workspace UI.

## Diagnostics Already Tried

• Cleared Electron/Chromium cache and profile data.
• Tested with GPU disabled:

--disable-gpu --disable-gpu-compositing
