I have the same issue, when my app tries to use websockets it crashes the webhost:

info: Aspire.Hosting.DistributedApplication[0]
      Login to the dashboard at https://localhost:17130/login?t=1219810f5d5e68bb166763b068b674a9
info: Aspire.Hosting.DistributedApplication[0]
      Distributed application started. Press Ctrl+C to shut down.

C:\Users\nicol\source\repos\MyApp\MyApp.AppHost\bin\Debug\net8.0\MyApp.AppHost.exe (processus 5872) s'est terminé avec le code -1 (0xffffffff).

Sometimes it works but the socket is disconnected in the middle:

System.Net.WebSockets.WebSocketException (0x80004005): The WebSocket is in an invalid state ('Aborted') for this operation. Valid states are: 'Open, CloseReceived, CloseSent'
   at System.Net.WebSockets.WebSocketValidate.ThrowIfInvalidState(WebSocketState currentState, Boolean isDisposed, WebSocketState[] validStates)

It works just fine when run the app without the apphost
