Environment
- Codex App: 26.803.10989.0 (Windows AppX package version)
- Computer Use plugin: 26.803.81509
- Platform: Microsoft Windows NT 10.0.26200.0 x64
- Subscription: ChatGPT subscription; exact tier unknown
Issue
Computer Use in the Codex desktop app cannot see or control any desktop apps on this Windows PC. The same account and workflow work normally on other computers.
Observed errors/states:
- Importing
@oai/skycan fail with:EPERM: operation not permitted, lstat 'C:\Users\<redacted>\AppData\Local\OpenAI\Codex'. - On retries where the module loads,
list_apps()andlist_windows()both return zero items even while WeChat is open. - Launching
C:\Program Files\Tencent\Weixin\Weixin.exeorWeixin.exemay fail with:failed to fetch shell:AppsFolder item: 找不到元素。 (0x80070490).
Result: Codex cannot open/control WeChat and cannot send a test message to File Transfer Assistant.
Reproduction
- Open the Codex desktop app on the affected Windows PC.
- Enable the Computer Use plugin/server and “Any App”, grant permissions, and unlock the session.
- Open WeChat manually.
- Ask Codex to use Computer Use to send a message to File Transfer Assistant.
- Computer Use either fails while loading
@oai/sky, returns zero apps/windows, or fails to launch WeChat with error0x80070490.
The same account and task work normally on other computers.
Expected behavior
Computer Use should enumerate the open desktop windows and interact with WeChat, as it does on the user's other computers.
Troubleshooting already attempted
- Unlocked the session and granted all requested permissions.
- Enabled “Any App”.
- Restarted and retried the Computer Use plugin.
- Reinstalled/retried the plugin.
- Fully uninstalled and reinstalled the official Codex Windows app; the problem persists.
No raw logs, session ID, or other PII are attached.

Additional reproduction and isolation from the same affected Windows machine:
list_apps(), selected and activated a returned window, captured window state/screenshots, clicked in the target window, and read the accessibility tree.node_replcall still works, but importing the bundled controller fails immediately with:await import("@oai/sky"), beforesky.list_apps()orsky.list_windows().node_modulesdirectory to the Node REPL search roots also did not resolve the same EPERM.Current environment:
26.803.10989.026.803.81509@oai/sky:0.6.610.0.26200This latest test isolates the failure to Computer Use runtime/module initialization rather than target-app visibility, approval, or launch behavior. No raw logs, session IDs, usernames, or unredacted personal paths are included.
Confirming this on another Windows 11 x64 machine with the same Codex desktop package version:
OpenAI.Codex_26.803.10989.0_x64__2p2nqsd0c76g0.@oai/skyloads, but the firstsky.list_apps()fails before any window can be enumerated with:Observed process setup: the sandbox permits the bundled
cua_noderuntimebinandnode_modulespaths, but not the parentAppData\\Local\\OpenAI\\Codexdirectory that the helper tries to inspect. This points to a sandbox path-allowlist regression rather than a target application or Windows ACL problem.Already attempted: Codex app Repair, full Windows restart, complete Codex restart, and a fresh Computer Use runtime session. All reproduce the same failure.
Impact: Computer Use cannot inspect or control an already-open Zoho Assist remote-session window, so no target applications are touched. No secrets, screenshots, session IDs, or user data are included.
I can confirm the same issue on another Windows system.
Environment:
26.803.10989.026.803.81509@oai/sky:0.6.6Computer Use still fails before selecting or interacting with any target application:
The problem reproduces after restarting Windows and Codex, re-enabling Computer Use, and starting fresh tasks. It is not target-app-specific; Calculator, Outlook, and WhatsApp attempts fail before app selection.
Windows ACLs were checked, and no security settings were changed. Please investigate this as the same Windows sandbox/runtime path regression reported here.
Update to my earlier report:
After updating Codex, the original Computer Use initialization failure is resolved on this machine.
Current versions:
26.810.4967.026.810.410470.148.0-alpha.9Fresh Node REPL test:
@oai/skyimported successfully.sky.list_apps()returned 40 apps.sky.list_windows()returned 4 windows.EPERM: operation not permitted, lstat ...\\AppData\\Local\\OpenAI\\Codexerror did not recur.This confirms that the latest update fixed the original runtime initialization/enumeration failure for me. I did not open, click, type, or inspect app content during verification.
