Windows desktop: unified exec fails at apply deny-read ACLs in every workspace

Description

Every local command fails before process creation in the Windows ChatGPT/Codex desktop app.

Exact error

Rejected("Failed to create unified exec process: helper_unknown_error: apply deny-read ACLs")

Reproduction

1. Open an existing local project.
2. Ask Codex to run a read-only command such as git status.
3. The command fails before execution.
4. Create and open a completely empty folder.
5. Ask Codex to read the current directory.
6. The same error occurs.

Troubleshooting already completed

• Fully restarted the ChatGPT/Codex desktop app
• Rebooted Windows
• Installed the latest available app update
• Retested in an empty folder
• Did not modify ACLs or run the app as administrator
• Did not attempt a sandbox bypass
• In-app feedback submission was also attempted but failed

Impact

No local shell command can start in any workspace. File editing, testing, and Git operations are blocked.
