Hello @Kane168 ,

Are you still experiencing this error? I just tested the Project and it is loading fine for me, I couldn’t reproduce your issue.

Hi Alberto

The condition remains. When “roslaunch moveit_setup_assistant setup_assistant.launch” is executed, this message appears “QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to ‘/tmp/runtime-user’”, not sure whether it matters or not.

That’s strange. Could you specify exactly at what Course/Unit are you getting this error?

In ROS Manipulation in 5 Days, Unit 6: Project, the beginning portion of
“Part 1 Build the MoveIt package”.

Hello @Kane168 ,

Can you try reloading the simulation? You can do this by clicking on the 3rd button in the simulation window.
