Codex App: plugin directory and computer-use settings fail with unknown variant `vertical`

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

What platform is your computer?

Microsoft Windows 11, Microsoft Windows NT 10.0.26200.0 x64

What issue are you seeing?

The Codex App fails to load the plugin directory and also fails to load the "Computer use" / management settings page.

Both screens show the same error:

Invalid request: unknown variant vertical, expected one of local, workspace-directory, shared-with-me

This prevents me from browsing/installing plugins and from using the related computer-use management settings.

I fully uninstalled Codex, removed local state as much as possible, downloaded and installed Codex again, but the issue still persists. This looks like a client/server schema mismatch or rollout issue: the server or plugin directory appears to return a vertical variant, while my Codex App/runtime only accepts local, workspace-directory, and shared-with-me.

Screenshots attached.

What steps can reproduce the bug?

1. Open Codex App on Windows.
2. Go to Plugins.
3. Observe that the plugin directory fails to load with:

Invalid request: unknown variant vertical, expected one of local, workspace-directory, shared-with-me

1. Go to Settings / Computer use / Management.
2. Observe the same error there.
3. Uninstall and reinstall Codex.
4. The same error still appears.

What is the expected behavior?

The plugin directory should load normally, and the Computer use management settings should load without schema/enum errors. If vertical is a valid new plugin/workspace category, older clients should either support it or receive a backwards-compatible response.

Additional information

This started after recent Codex plugin rollout changes. It appears unrelated to a corrupted local install because a full uninstall/reinstall did not fix it.

Related context: recent Codex issues show similar client/server enum/schema mismatch failures in remote context compaction, for example unknown variant auto, expected high or original.
