What platform is your computer?
Microsoft Windows NT 10.0.22631.0 x64
What issue are you seeing?
The Codex App cannot start the unified exec terminal helper.
Exact error:
Failed to create unified exec process: helper_unknown_error: setup refresh had errors
The failure occurs before any command starts, including read-only commands such as:
git rev-parse HEAD
Reproduced in:
- the existing project chat;
- a newly created chat in the same local project;
- after restarting the Codex App;
- after restarting Windows;
- after Workspace dependency diagnostics reported
Codex dependencies look healthy;
- after reinstalling the Workspace bundle;
- with
[windows] sandbox = "elevated";
- with
[windows] sandbox = "unelevated".
The local project path contains Cyrillic characters. The project and commands worked previously with the same path.
Expected behavior:
The unified exec helper starts and executes the read-only command.
Actual behavior:
The helper fails during setup refresh before the command is launched.
Impact:
Terminal preflight cannot run. Repository staging and commit operations are intentionally paused. No repository changes, staging, or commits were performed during troubleshooting.
The existing .codex/.sandbox/sandbox.log does not contain the current failures. Its last records predate the currently installed Codex App version.
Feedback ID:
01a03853-2618-7b90-9ce3-1d74d3c81a1d
What steps can reproduce the bug?
- Open the Codex App on Windows.
- Open an existing local-project chat or create a new chat in the same project.
- Ask Codex to run a basic read-only terminal command such as
git rev-parse HEAD.
- The terminal helper fails before the command starts with:
Failed to create unified exec process: helper_unknown_error: setup refresh had errors.
- Repeat after restarting the app or creating another project chat; the same failure occurs.
What is the expected behavior?
The unified exec terminal helper should initialize successfully and execute the requested command in the configured local project directory.
