What's included

  • Setup refresh exits with "helper_unknown_error: setup refresh had errors" during ACL work: os error 32 or 5 on cua_node runtime files, stale or over-long runtime paths, a NUL-filled deny_read_acl_state.json, Google Drive or WSL UNC workspaces, or Administrators-owned folders
  • "sandbox provisioning failed" with helper_sandbox_lock_failed, access denied on %USERPROFILE%\.codex\.sandbox-bin, returning after an ACL repair
  • "Setup stopped" right after Retry setup with no UAC prompt, then "registered Core setup has not completed"
  • Sandbox preparation refuses to run: "managed networking requires the elevated Windows sandbox backend" or "cannot enforce split writable root sets" in Work, delegated or scheduled tasks
  • CreateProcessSecurityEnvironment fails with HRESULT 0x80070020 before any command starts

Not included

  • Command failures on macOS or Linux sandboxes
  • Commands that start but then fail or time out inside the sandbox
  • Approval prompt or permission-mode behavior once commands do run
