@wolverinevn have you tried to uninstall uvloop by running the command pip uninstall uvloop inside of your virtual environment?

No yet because I'm not sure what uvloop is doing. Will try.

Hey there @home-assistant/core, mind taking a look at this issue as its been labeled with a integration (shell_command) you are listed as a codeowner for? Thanks!

Shell_command works well after uninstalling uvloop. In my case, with:
docker exec homeassistant pip3 uninstall -y uvloop

I appreciate your assistant so much.

I'm keeping this issue opening cause it still be a bug.

Great to hear that this solved your problem!

No problem at all.

Sure thing, I am curious too why uvloop is not a requirements for home-assistant/home-assistant but is a requirement for home-assistant/hassio-homeassistant.

@pvizeli can you explain this difference to us? Thank you 😊
