Cannot run tests

[Eclips4]

On current main, I got this:

Probably from #102853, cc @itamaro.

[Eclips4]

However.. I just rebuilt an interpreter and now tests are ok.
Please, add pending label until I find way to reproduce it =)

[JelleZijlstra]

Might be related to whether the _asyncio accelerator module exists? Just guessing.

[itamaro]

my guess: if you pulled main without rebuilding the interpreter, you got an old Task type from the accelerator module mixed with new eager task factory from the tasks python module

[Eclips4]

Yeah, @itamaro you're right!
Sorry for making noise
