Thanks in advance
your mesh is not very healthy. first you have some normals reversed, UnifyMeshNormals only brings partial results, meaning you have some deeper issues like faces are folding in on itself or practically doubling strangely, you might have to rebuild that, specifically in that area where those stairs are. just delete all the parts which you find and rebuild them manually. you might also want to find a better way getting to that input geometry it is quite a mess.
