Additional information

It's a shutdown-issue

First, based on my execution logs, I can confirm this is a shutdown issue.

It's additional tickets related to #4463, which behaviors in nav2_theta_planner

Below is an analysis of the cause of this bug:

The action_server_ binds the nav2_planner::PlannerServer::computePlan() function as a callback function,

and using the nav2_theta_star_planner->getPlan() , which may access the early shutdown costmap_ros_:

navigation2/nav2_theta_star_planner/src/theta_star_planner.cpp

Lines 181 to 190 in 9fbae3e

	void ThetaStarPlanner::getPlan(
	nav_msgs::msg::Path & global_path,
	std::function<bool()> cancel_checker)
	{
	std::vector<coordsW> path;
	if (planner_->isUnsafeToPlan()) {
	global_path.poses.clear();
	throw nav2_core::PlannerException("Either of the start or goal pose are an obstacle! ");
	} else if (planner_->generatePath(path, cancel_checker)) {
	global_path = linearInterpolation(path, planner_->costmap_->getResolution());

This issue would be fixed in humble by PR #4463

This issue would be fixed in Iron by my later PR

[GoesM]

because it's an additional ticket, so I close it ^_^
