I still can't send queued messages after editing them in the main chat

I'm still having trouble with queued messages in the main chat on Windows. Queuing messages in side chats works for me now, but editing a queued message in the main window can still leave me unable to send it.

The error is:

App-server queued follow-up no longer exists

This happens when I queue a message while a task is running, click Edit, change the text, and try to send it again. I just want to correct a pending instruction and put it back in the queue.

My installed Windows package is 26.908.9136.0, checked on September 17. I saw the reply saying a fix was coming in the next release, but I don't know whether this version includes it. Could you confirm which Windows version fixes this?

Related: #44781 for the edit error and #45087 for side-chat queuing. I'm opening this separately to track the main-chat problem that I'm still seeing.

For context, a local patch installation was attempted earlier but failed, so those queue changes never took effect. The temporary files were removed.

Start by reproducing the Windows main-chat flow: queue a message during a running task, edit it, and resend it; then trace the main-chat edit/resend path and the app-server queued follow-up lifecycle. Done means the edited message can be placed back in the queue without the “no longer exists” error, while side-chat behavior remains working.
