CreateProcessAsUserW failed: 5 on Windows 11 Home — local runner fails

What version of the Codex App are you using (From “About Codex” dialog)?

Version 26.611.61049 • Released Jun 16, 2026

What subscription do you have?

Pro

What platform is your computer?

Windows 11

What issue are you seeing?

Local runner fails with CreateProcessAsUserW failed: 5 (ERROR_ACCESS_DENIED) on Windows 11 Home. Steps tried: granted SeAssignPrimaryTokenPrivilege + SeIncreaseQuotaPrivilege via secedit, rebooted, ran as Administrator. Docker Desktop is running and healthy. Error persists regardless.

What steps can reproduce the bug?

Check workspace

What is the expected behavior?

I tried to check C:\Projects\FCC, but the local command runner is currently blocked by Windows before any workspace command can start:
windows sandbox: runner error: CreateProcessAsUserW failed: 5
I also checked for app-exposed workspace resources, but only plugin metadata is available, not the project files. So I can’t reliably inspect the folder contents or git status from this thread yet.
The workspace path itself is set correctly as C:\Projects\FCC; the issue is the process launcher permission, not the directory name.
