HCCleanupAsync deadlock on HCWebSocketConnectAsync failure.

まず XBOX GDK 250402 で HCWebSocketConnectAsync の 401 失敗を再現し、次に WebSocket のクリーンアップパスを通じて HCCleanupAsync を追跡します。WinHttpConnection::StartWinHttpClose と、ログに示されている WinHttpCloseHandle の失敗を調査します。接続に失敗した後もデッドロックせずにクリーンアップが完了すれば完了です。

On XBOX GDK 250402 version after HCWebSocketConnectAsync failure(401 error code from http), the HCCleanupAsync creates deadlock and cannot be finished or even terminated. Possible reason that I found in logs is :

[0758][I][16:01:09.365][HTTPCLIENT] WinHttpConnection WinHttp callback statusCode=11

WinHttpCloseHandle couldn't be cleaned up, so it provokes deadlock.
Logs when I invoke HCCleanupAsync:
