Windows: pausing Goal Mode still injects a continuation; restoring its in-app browser silently closes Codex #33827

What version of the Codex App are you using?

• Microsoft Store package: OpenAI.Codex_26.707.12708.0_x64__2p2nqsd0c76g0
• Package status: Ok

What platform are you using?

Windows x64, native PowerShell/Codex Desktop.

What happened?

A long-running Goal Mode task repeatedly causes Codex Desktop to silently close/restart when its in-app browser session is restored. Pausing the goal does not fully stop the sequence: the persisted task record shows the goal becoming paused, followed immediately by another internal goal-continuation prompt in the same interrupted turn.

There is no corresponding Windows Application Error / Application Hang event for these closes and no Crashpad report. The Codex desktop log simply stops, followed by a fresh main-process session.

This appears to be an interaction among:

1. Goal Mode pause/continuation state,
2. interrupted or orphaned task lifecycle records,
3. thread resume restoring an in-app-browser webview, and
4. renderer/main-process termination without a recoverable error page.

Reproduction sequence observed

1. Run a long-lived Goal Mode task that uses Browser Use against a local frontend.
2. Reload/reopen Codex while the task has interrupted history.
3. Pause Goal Mode.
4. Codex persists status: "paused", but an internal Continue working toward the active thread goal prompt is recorded immediately afterward.
5. The task restores its Browser Use sidebar/webview and navigates to http://127.0.0.1:3000/.
6. Codex silently closes/restarts.
7. Reopening the same task repeats the browser restoration and close.

Two earlier app sessions ended with the same affected task restoring the same Browser Use webview and loading 127.0.0.1:3000 immediately before their logs stopped.

Saved task-state evidence

The affected rollout is valid JSONL but unusually large (about 71 MB) and has unbalanced lifecycle counts:

task_started:  193
task_complete: 187
turn_aborted:    1

The most recent task_started has no matching task_complete. Several earlier Goal Mode turns are also unmatched after previous silent closes.

On resume, the desktop log reports the latest turn as interrupted while still setting the task to streaming:

latestTurnStatus=interrupted markedStreaming=true

Additional startup signal

During one restart, bundled-browser-plugin reconciliation also attempted to uninstall/reconcile browser@openai-bundled and failed with:

failed to remove existing plugin cache entry: Access is denied. (os error 5)

The browser plugin subsequently loaded, so this may be secondary, but it could contribute to stale Browser Use state.

Expected behavior

• Pausing Goal Mode should prevent further automatic goal-continuation prompts.
• An interrupted turn should be persisted or synthesized as interrupted/failed with a balanced lifecycle.
• Restoring a thread with a stale Browser Use session should either restore cleanly or discard the stale browser route.
• A renderer/webview failure should show a recoverable error instead of silently closing the desktop app.

Actual behavior

• A goal continuation remains after the goal is persisted as paused.
• The task remains lifecycle-unbalanced and is resumed as streaming despite being interrupted.
• Restoring its in-app browser repeatedly correlates with silent app termination.
• Windows and Crashpad do not record a conventional application crash.
