Windows Store version cannot access network: AppContainer blocks all outbound TCP

Environment

• OS: Windows 11
• Codex version: 26.602.9276.0 (Microsoft Store)
• Install path: WindowsApps\OpenAI.Codex_26.602.9276.0_x64__2p2nqsd0c76g0

Issue

All network requests from within Codex fail with:
WinError 10013: An attempt was made to access a socket in a way forbidden by its access permissions

Diagnosis

• DNS resolution: ✅ working
• Host network: ✅ netstat shows many active HTTPS connections
• Windows Firewall outbound rules: ✅ no blocking rules
• System proxy: ✅ direct connection, no proxy
• Codex sandbox TCP: ❌ Python / PowerShell / curl all blocked
• Thread sandbox policy has networkAccess: false; requesting network permission is auto-rejected due to sandbox_approval policy

Suspected cause

The AppContainer isolation layer in the Windows Store version appears to be blocking outbound TCP at the OS level. The app manifest may not declare the internetClient capability.

Request

1. Can you confirm whether the Windows Store version has AppContainer network restrictions?
2. Is a standalone installer (.exe) available for download? Could not find one on codex.chat or GitHub Releases.
3. Any workaround in the meantime?
