What version of the Codex App are you using (From “About Codex” dialog)?
Version 26.616.51431 • Released Jun 20, 2026
What subscription do you have?
Pro
What platform is your computer?
Microsoft Windows 10.0.26200.8655 x64; Codex App running with WSL agent environment and WSL terminal.
What issue are you seeing?
Computer Use / Computadora does not initialize correctly in Codex App when the project/thread is running from WSL.
The plugin appears installed and computer-use-client.mjs exists, but the runtime fails before it can list Windows apps/windows.
I reproduced two related initialization errors:
codex/sandbox-state-meta: missing field sandboxPolicy
And in a later fresh session:
codex/sandbox-state-meta: sandboxCwd is not a local file URI:
file:///mnt/c/Users/nirst/Documents/Codex/2026-06-22/...
The failure happens before any Windows app automation runs.
What steps can reproduce the bug?
- Open Codex App on Windows.
- Open a project stored in WSL, for example
/home/pilsenir/projects/sfo-web.
- Use WSL as the agent environment and WSL terminal.
- Ask Codex to use Computer Use / Computadora.
- Try a minimal smoke test, such as listing available Windows apps/windows.
- Computer Use fails before listing apps/windows.
I also reproduced this after restarting Codex App and starting a fresh session.
What is the expected behavior?
Computer Use should initialize successfully from Codex App and either list controllable Windows apps/windows or show a recoverable configuration/setup error.
It should not fail before app/window listing because the project is running from WSL.
Additional information
Normal WSL tooling is working in the same environment:
- Node/npm work.
- GitHub CLI works.
- Browser opener works.
- Repo typecheck/tests work.
This appears isolated to the Computer Use / Windows automation runtime, not the repo shell environment.
I also reported this through Codex App /feedback from the affected session.
