Hi guys, I use this link http://wiki.ros.org/mpc_local_planner for mpc. when I run

roslaunch mpc_local_planner_examples carlike_minimum_time.launch

everything is fine, no error or warning.

but when I set a goal with 2D Nav Goal , error happens.

Here is the error msg:

[move_base-3] process has died [pid 240428, exit code -11, cmd /opt/ros/noetic/lib/move_base/move_base __name:=move_base __log:=/home/loren/.ros/log/b04678b0-fc67-11ed-bd54-d1dcc34a72bd/move_base-3.log].
log file: /home/loren/.ros/log/b04678b0-fc67-11ed-bd54-d1dcc34a72bd/move_base-3*.log

Will, I can't not uploda pic. sorry!

BTW: my os is ubuntu20.04, ROS is noetic.
