Same here.

I've followed typical Gazebo install instructions on Ubuntu 24.04. I can run gz sim for example. Still looking into this.

Fix: follow local gazebo model setup instructions here https://github.com/MOGI-ROS/Week-3-4-Gazebo-basics?tab=readme-ov-file#run-gazebo-examples

set your GZ_SIM_RESOURCE_PATH to the downloaded folder from the drive provided in Week 3-4.
