Session file is corrupted - Invalid literal value

SessionFeature.Lifecycle.cs の215行目にある報告された SessionFeature.LoadSession 呼び出しから開始し、SDK の ResumeSessionAsync パスを追跡します。355行目付近の破損したセッションデータ、特に ephemeral フィールドを調査し、再現可能な失敗または無効なセッションファイルを処理するための明確な修正を特定します。

I'm using the .NET SDK, a few times now, after updating the NuGet version, some (not all) previous sessions become corrupt. This is the error i get when resuming a session -

System.IO.IOException: Communication error with Copilot CLI: Request session.resume failed with message: Session file is corrupted (line 355: ephemeral: Invalid literal value, expected true)
