Hello,

I am trying to launch the gazebo simulation. When I run the gz command on the introduction. It shows me help commands. it does not launch the gazebo simulation

could you please help

Please let us know the exact unit of the course you are working on, and please share some screenshots so we can understand your situation better.

I believe my instance was blocked by my computer and I used another computer and it worked. I closed the instance and launched it again and it worked. I was trying to open Gazebo sim on intro to gazebo ros2 and I had these issues. Everything is working now, Thank you!
