Failed Vision bricks session

Attempting to use Vision when it's not enabled (both by the model and my org) bricks my conversation causing me to lose the session history. All subsequent prompts after a failed vision attempt produce the below.

As this was in the desktop, there does not appear to be a rewind (escape-escape) feature available here. That could reset the session to before image files were added.

Execution failed: CAPIError: 400 {"error":{"code":"bad_request","type":"websocket_error","message":"vision is not enabled for this user or integration (model \"gpt-5.5\")"}} (Request ID: 00000-d13499b6-dfcf-484e-a57f-8cd77e4ebf72)

デスクトップアプリの /chat フローから開始し、モデルと組織で Vision が無効になっている状態で Vision を試して失敗を再現します。CAPIError websocket エラーが後続のプロンプトとセッション履歴にどのような影響を与えるかを確認します。失敗した試行の後も履歴を失わずに会話を引き続き利用できれば完了です。
