This issue is similar to #13917, and both remain unsolved.

Through debugging, I discovered that the issue lies in the following code:

https://github.com/openai/codex/blob/db5781a08872873a4df82fbb4b3dc6ffd98b5d15/codex-rs/windows-sandbox-rs/src/elevated_impl.rs#L391-L392

After write_frame, the call to read_spawn_ready returns a result indicating that the command execution failed:

[2026-03-19 17:21:24.310 codex.exe] START: C:UserswangzAppDataLocalMicrosoftWindowsAppspwsh.exe -Command [Console]::OutputEncoding=[System.Text.Encoding]::UTF8;

echo hello dbg" | env_u16_len=7190 | si_flags=256 | creation_flags=1024

This error occurs when codex-command-runner.exe executes the following code:

https://github.com/openai/codex/blob/db5781a08872873a4df82fbb4b3dc6ffd98b5d15/codex-rs/windows-sandbox-rs/src/process.rs#L126-L138

It appears to be a permissions issue. I also noticed that the account used in the following code is CodexOffline:

https://github.com/openai/codex/blob/db5781a08872873a4df82fbb4b3dc6ffd98b5d15/codex-rs/windows-sandbox-rs/src/elevated_impl.rs#L309-L327

Therefore, I granted the CodexOffline account read and execute permissions for the C:/Users/wangz directory via File Explorer, but the same error persists.

Since codex-command-runner.exe is loaded at runtime, I am unsure how to debug it. Furthermore, even after modifying None in the following code to a log file path, no logs are generated, likely due to permission issues preventing file writes:

https://github.com/openai/codex/blob/db5781a08872873a4df82fbb4b3dc6ffd98b5d15/codex-rs/windows-sandbox-rs/src/process.rs#L226-L236

I do not understand why new accounts like CodexOffline and CodexOnline need to be created instead of simply using the local Windows user account.

@AnonTokio It's probably the issue reported here: https://github.com/openai/codex/issues/10090, some permission issue when PowerShell is installed via the Microsoft Store. Try uninstalling PowerShell and reinstall it via the MSI installer, that fixed it for me.

@chausner Thanks! After uninstalling PowerShell and reinstalling by scoop, the problem is resolved. This may be related to the permissions of the AppData folder.
