Open3D quits abnormally when visualising a number of cubes about open3d

[chrhoehl]

Following was solved by downgrading to numpy 1.26.4. Keeping it here as reference because the behavior looked similar to the one reported in the initial issue description.

Same with Open3d 0.18.0 installed through pip on python (Windows 11, 64bit)

• 3.10.11 embedded ( 3.10.11 (tags/v3.10.11:7d4cc5a, Apr 5 2023, 00:38:17) [MSC v.1929 64 bit (AMD64)])
• 3.11.7 embedded,
• 3.11.9 full install

On 3.10.11 I also tried with Open3d 0.17.0 / 0.16.0, which produces the same behavior.

Other operations here fail, too:

• PointCloud.transform
• o3d.pipelines.registration.registration_icp

Alternative way to reproduce (on draw-operation):

python -c "import open3d as o3d; \
           mesh = o3d.geometry.TriangleMesh.create_sphere(); \
           mesh.compute_vertex_normals(); \
           o3d.visualization.draw(mesh, raw_mode=True)"

Replacing the draw-operation with o3d.visualization.draw_geometries([mesh], window_name='Mesh Visualization', width=800, height=600) produces a window that visualizes the mesh without memory corruption

@chrhoehl I think your error is due to numpy v2 incompatibility and unrelated to the reported error.

@ssheorey Many thanks, downgrading to 1.26.4 solved my problem! With your suggestion I also found this described in #6840
