Can you check your LD_LIBRARY_PATH by sudo echo $LD_LIBRARY_PATH Looks it's a problem with your QT

running sudo echo $LD_LIBRARY_PATH I'm getting /opt/ros/melodic/lib

So, how to solve this issue

Try first to update your system and do a rosdep update. It's correctly mapped.

By any chance are you running on WSL?
