Describe the issue

I load a triangle mesh into open3d, call mesh.filter_smooth_taubin and save the filtered mesh to disk. The result contains a lot of nan which is not expected.

Steps to reproduce the bug

import open3d as o3d


if __name__ == '__main__':
    mesh = o3d.io.read_triangle_mesh('./input.ply')
    out = mesh.filter_smooth_taubin(2)
    o3d.io.write_triangle_mesh('./output.ply', out)

Error message

No response

Expected behavior

I expect no nan generated.
