Reproduce the Windows 11 failure by connecting with openvpn3 3.7.0, then disabling the TUN network adapter. Start at openvpn::TunWin::WintunClient::read() and stop(), following cleanup through TunWrapTemplate::close() to Asio's win_iocp_handle_service destruction. Done means the adapter failure is handled without the invalid-handle crash.
