Crashes in Windows 10

[alencodes]

Frequently this happens with command shell opened in windows 10.
Just tried repeatedly printing a variable

It might be a duplicate of #12049

and (mr meeseeks only reply to comments, not to original issues when you submit)

Hey so I've been running into this issue as well. This is by no means an actual fix; however, does the problem seem to stop if you do the following?

import asyncio
asyncio.log.logger.setLevel(50)

I'm still not sure why the eventloop complains so often; however using the PYTHONASYNCIODEBUG environment variable allows you to inspect what's going on a little bit more, and there I realized that the default logger for asyncio has it's level set to INFO which causes incessant blocks to the REPL. I think.

I tried that way @farisachugthai , Still the same error pop up.

Issue is reproducible in updated version also
