Case-ID: 17935956 In the NetworkExtension framework, for the NETransparentProxyProvider and NEDNSProxyProvider classes: when calling the open func writeDatagrams(_ datagrams: [Data], sentBy remoteEndpoints: [NWEndpoint]) async throwsin the NEDNSProxyProvider class, and the open func write(_ data: Data, withCompletionHandler completionHandler: @escaping @Sendable ((any Error)?) -> Void)in the NETransparentProxyProvider class, errors such as "The operation could not be completed because the flow is not connected" and "Error Domain=NEAppProxyFlowErrorDomain Code=1 "The operation could not be completed because the flow is not connected"" occur. Once this issue arises, if it occurs in the NEDNSProxyProvider, the entire system's DNS will fail to function properly; if it occurs in the NETransparentProxyProvider, the entire network will become unavailable.
