Crashes in Windows 10

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

Unhandled exception in event loop:

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.
