Reproduce the WDA launch with tidevice 0.7.13 on iOS 14.7, then trace cmd_xctest in tidevice/__main__.py through connect_instruments and create_inner_connection in tidevice/_device.py. Inspect switch_to_ssl in tidevice/_safe_socket.py and the reported SSL handshake timeout; done means WDA launches without this timeout.
