Ian,

`MyProtocol` does not provide an `__init__()`, and thus
```
super().__init__()
```
is calling the `__init__()` from `Protocol`. This results in the `TypeError`.

Simply remove `super().__init__()` to resolve your issue.

This behavior was changed in https://github.com/python/cpython/pull/27545 (see `Lib/typing.py:1384`); I don't see what you are reporting as a regression, I see it as correct behavior that I would expect. Apologies if you feel differently.

Cheers,
Julian
