i’m working on a 2 wheel autonomous robot simulation with ROS2 and Gazebo. when never I launch this file gazebo sever crashing error Therefore im trying to setup ros2_control, but i got quiet some problems with it:

My setup: Ubuntu 22.04 Ros humble Gazebo 11.10.2

ros2 launch autonomous_bot launch_sim.launch.py

Can you show your package.xml file. I guess the issue must be because the gazebo isnt getting the urdf file correctly and crashing.
