Hi, you see the point cloud only because your Rendering settings/Max triangles to display is set to 141 M tris:
and you model has over 180 M tris:
To see the mesh you can change the settings to show more triangles (the maximal value is restricted by your GPU) or simplify the model under 140 M tris.
Also, what were your texture settings? As the point cloud is B&W, is it possible that the Texturing style was set to Intensity? If so, can you try to use Visibility, Photo-consistency or Mosaicking based texturing?
