Hello, Any news about this bug ?

This has been fixed as of v1.0.10. The root cause was stale WebSocket state being reused after a reconnection, which triggered the "input item ID does not belong to this connection" error. Updating to the latest version should resolve this. If you're still seeing this on a current version, please feel free to reopen.

This has NOT been fixed within VS Code. IDK about GH CLI, but this issue is still occurring within the chat interface of VS Code.
See microsoft/vscode#318482

Still seeing this on Copilot CLI v1.0.79-4

I ran into this on 1.0.81-12. It happened after I exited, restarted and resumed the session. It only recovered after switching between models.

It happens to me if a session launches with a different user than I want (e.g. personal vs work) and does a message and then I switch user. It's like it's trying to access data that is keyed under the previous user or something and it just fails. I have to rewind conversation enough that it goes away seems like. Just restarting doesn't fix it.

I was able to workaround the issue without losing the existing session by creating a /fork
