Summary:
The Codex Windows app crashes immediately after launch. The Microsoft Store app is installed and the package status is Ok, but the app exits within about 10 seconds and creates a Crashpad dump every time.

Environment:

  • Codex Windows app: 26.608.1337.0
  • Codex CLI: 0.139.0
  • OS: Windows 11 Home 10.0.26200 x64
  • Display adapter: Intel(R) UHD Graphics 620
  • Display driver version: 26.20.100.7323

Steps already tried:

  • Repaired the app with winget repair --name Codex
  • Reset the Codex AppxPackage
  • Uninstalled and reinstalled the Codex Microsoft Store app
  • Launched with --disable-gpu
  • Launched while blocking the persistent.oaistatic.com update manifest request

Result:

  • The app still exits shortly after startup.
  • The Codex CLI continues to work normally.
  • The %USERPROFILE%\.codex directory and CLI configuration were preserved.

Crash observations:

  • Exception code: 0xE06D7363
  • Throw module: KERNELBASE.dll
  • The stack repeatedly includes this module:

Privacy note:
I am not attaching auth.json or any files from %USERPROFILE%\.codex. I can provide the Crashpad dump if a maintainer needs it.
