ROS2 Galactic demo_nodes_cpp talker does not output anything.

edit

I followed the instructions per https://docs.ros.org/en/galactic/Inst... to install ROS2 Galactic on Windows but when I run demo_nodes_cpp talker, I get no output at all. Not even an error or warning. I tried uninstalling and reinstalling to see if that would fix the issue, but it didn't. Did anyone else have this issue?
