56652209ec`StdioTransport` subclasses validate the command before calling `super().__init__()`, so an object whose construction raised never got a `_stop_event`. Garbage collection then ran `__del__`, which dereferenced it, and CPython printed an unraisable `AttributeError` on stderr — burying the error the caller was meant to see (`PythonStdioTransport`, `NodeStdioTransport` and `UvStdioTransport` can each reach that path). `__del__` now reads the event with `getattr` and skips it when the instance never finished initialising.
