I don't have that issue but did encounter it in other ROS packages. It's because your executable RGBD.so under ROS/ORB_SLAM3 can't find libDBoW2.so. Go to the ROS/ORB_SLAM3 folder and type:

ldd -r ./RGBD | grep DBoW

It should show something like

libDBoW2.so => <your folder>/ORB_SLAM3/Thirdparty/DBoW2/lib/libDBoW2.so (0x00007feae2efc000).

If it doesn't it means it can't find it or found DBoW2 elsewhere. I had this issue where it linked to DBoW2 from another ROS workspace because I had that workspace sourced in my bashrc when building the package. Make sure to only source setup.bash from /opt/ros and no other workspace and then build again (you should probably delete the build folder inside the ROS workspace before building again).
