1 year ago I am not sure how it is possible as you are using mambaforge, but in your mamba list it is possible to see that you are mixing packages from the main channel and the conda-forge one, that is not supported.
I suggest you to:
- Remove the symbolic link from
/usr/localto~/mambaforge/envs/ros_env/lib, as it is not solving any problem and actual creates more - Can you create a new clean environment following the instructions in https://robostack.github.io/GettingStarted.html
- After you do so, you should do
mamba listand check that all packages either come fromconda-forgeorrobostack-staging
After you do this, I suggest to try again doing the compilation and check if you have still problems.

I created the link from ~/mambaforge/envs/ros_env/lib to the '/usr/local/lib'
sudo ln -s ~/mambaforge/envs/ros_env/lib /usr/local/Then compile, source and run build again, I got:
I was examining the CMakeLists.txt file and decided to remove a specific section:
The compilation process completed successfully without any errors. However, when I attempted to launch the build file, I encountered an error.
