Yesterday I was working on my Rosject project for the ROS2 in 5 days course and everything was fine. Today I loaded it up and a wall on gazebo has moved and the robot is not spawning in. I haven’t made any changes to any files since it was working fine yesterday. Here is the error log I get when running the gazebo command.
Thanks!
