Can you give some information on what steps you followed to install Humble?

Thank you for your reply.
I followed the the official documentation
https://docs.ros.org/en/humble/Installation/Ubuntu-Install-Debians.html

So it kind of looks like the installation isn't correct, for some reason. Can you tell us:

  1. What commands you were running at the time
  2. What ls /opt/ros/humble/lib/x86_64-linux-gnu/libddsc* shows?

I have the same situation, you can try sudo apt-get install -y ros-humble-rmw-cyclonedds-cpp

I found the solution for this.
Just put /opt/ros/humble/lib/x86_64-linux-gnu in your ld config file.
