Adding MoveIt2 #include Line(s) Breaks VS Code IntelliSense

[halonaK]

I'm experiencing an issue where adding MoveIt2 headers to my C++ project in VS Code causes IntelliSense to stop working.

For example, when I include the following line in my ROS 2 package:

#include <moveit/move_group_interface/move_group_interface.h>

IntelliSense stops providing suggestions, including for rclcpp components that were previously working fine.

However, if I remove the MoveIt2-related #include statement, IntelliSense resumes working correctly.

What I've Tried

• Reinstalled VS Code and checked all related settings (settings.json, c_cpp_properties.json)
• Verified that compile_commands.json is correctly generated (colcon build --cmake-args -DCMAKE_EXPORT_COMPILE_COMMANDS=ON)
• Ensured that C_Cpp.default.compilerPath is set correctly

Possible Causes?
Could this be a VS Code bug, or is there a specific configuration needed for MoveIt2 headers? Any advice or known fixes would be greatly appreciated.

Does the same thing happen if you only include the newer .hpp files? (I wonder if it's getting confused by some of the deprecation macros or something in the plain .h files)
