OpenAI Codex Bug: Windows Computer Control Fails with EPERM Despite Granted Permissions
zouzhi27neverz · ghdev · 2026-08-13
A user reported a permission control bug in the OpenAI Codex desktop app on Windows via GitHub. When attempting to use the computer control plugin to list open windows, calling sky.listwindows() fails immediately with an EPERM error.
The reporter noted that even after explicitly granting read permissions to the app directory and restarting multiple times, the system still returns Access is denied. This prevents the plugin from reading or switching any windows, suggesting a potential issue in how the Windows sandbox passes file system permissions to the underlying Node runtime.
