   English translation:

   The app loads indefinitely when launched on Windows 10 / OpenAI.Codex 26.924.2738.0.
   The issue persists after rebooting, repairing and resetting the Windows app, and separating the web profile.
   In doctor, the DB, thread list, and connection checks all pass. However, the app logs show that after app-server initializes successfully, app_start fails with a timeout after approximately 123 seconds. doctor shows an update to 26.924.6891.0, but Microsoft Store and winget report that no updates are available.

   Update (September 30, 2026)

   The issue still occurs on Windows 10 after updating to OpenAI.Codex 26.928.1915.0. The installed package reports Status: Ok. The entire app remains on a black splash screen with the OpenAI logo; no sidebar or message composer appears.

   Troubleshooting completed without recovery:

   • Windows app repair and reset
   • Updating with the latest installer
   • Restarting only the renderer (no momentary recovery)
   • Minimizing the app for 10 seconds and restoring it

   Recent app-log observations:

   • Local executor rendezvous succeeds.
   • config/read, thread/list, and some thread/read requests succeed.
   • Authentication and Orbit requests return HTTP 200.
   • The codex-home entry reports hostId=undefined.
   • fs/readFile returns error -32602 requiring an environmentId.
   • The durable WebSocket handshake succeeds.
   • Some cloud thread/read requests are followed by "Conversation state not found".

   These are observations only; I have not established the root cause, and these errors do not establish that local conversations have been lost.

   A copied backup of the local Codex data directory exists. Its completeness, database integrity, and restorability have not been verified.

   Could you provide a fixed build or a supported, safe workaround that preserves local-only conversations, attachments, and project mappings? Before any further destructive reset, data-directory deletion, or reinstall procedure, I need specific official guidance on what to back up and how to restore it. Please also clarify whether the environmentId/hostId and conversation-state errors above are relevant to the startup failure.

   One additional observation: I have fully exited the desktop app from my perspective, but through Remote on my iPhone I can still open and use conversations that previously appeared only on the PC. Remote reports that only the app window was closed, which conflicts with the shutdown state I observe on the PC.

   There is no obvious app icon in the taskbar or expanded system tray. This is a UI observation, not a process inventory; I have not verified that every background process or service has stopped.

   Could you explain the expected background-process lifecycle after exiting the desktop app, why Remote can still access these conversations, and whether this apparent state mismatch could be related to the black-logo startup failure? Please advise on a supported recovery path that preserves the existing conversations and attachments.
