The robot disappears from the visualization and does not return unless the URDF is reloaded manually whenever there are errors in the URDF file. For example, starting a new geometric shape with <box without finishing the line will make the robot disappear. In order to bring back the robot, the error needs to be corrected in the file and the visualization needs to be closed and opened again.
