Thanks Andrew for heads up.
*1. My laptop (Windows 10) *with no changes runs happily with no error from
here.
python 3.8.5
asyncio 3.4.3
2. *My Windows VM (AWS EC2)* is where the whole mess is happening. I *upgraded
*from Python 3.8.5 to 3.9.7. Asynio stayed 3.4.3, no change.
I manually overwrite C:\ProgramData\Anaconda3\Lib\asyncio\task.py with
what's here https://github.com/python/cpython/pull/31441/files
(Only
https://github.com/asvetlov/cpython/blob/150ef068c77abc6a5e7ba97397ac65113dba355a/Lib/asyncio/tasks.py
)
Before I made this change, the error was:

After I upgraded python to 3.9.7 and overwrite task.py, a different error
(but also in asyncio stack):
