ugv_gazebo_sim I want to run the file roslaunch hunter2_gazebo hunter2_gazebo.launch. BUT Segmentation fault (core dumped)

I want to run the file roslaunch hunter2_gazebo hunter2_gazebo.launch. However, I encounter the following error message. What should I do?

I edit hunter2_gazebo.launch like this

  <arg name="world_name" default="$(find limo_gazebo_sim)/worlds/empty.world"/>

  <include file="$(find gazebo_ros)/launch/empty_world.launch">
	<arg name="world_name" value="$(arg world_name)"/>
        <arg name="paused" value="false"/>
        <arg name="use_sim_time" value="true"/>
        <arg name="gui" value="true"/>
        <arg name="headless" value="false"/>
        <arg name="debug" value="false"/>
  </include>

problem solved
