What issue are you seeing?

Codex shell execution appears stuck on trivial commands. On June 5, 2026, a minimal PowerShell command such as Write-Output 'ok' did not return in the session. The same sanity check was then delegated to a
sub-agent, and that sub-agent also remained running for 60 seconds without returning any result and had to be shut down manually. There was no useful shell output, timeout message, or normal completion
result.

What steps can reproduce the bug?

1. Start a Codex session.
2. Ask Codex to run a any / trivial shell command such as Write-Output 'ok'.
3. Observe that the command does not return promptly.

What is the expected behavior?

Codex being able to use shell commands.
