Jupyter Lab Python Kernel crashes when I try to close the visualization window

Describe the issue

In Jupyter lab, I try to render an STL file using the open3d.visualization.draw_geometries() method. When I run the program, I get an error: "Cocoa: Failed to find service port for display", however a window pops up as expected, showing my successfully rendered geometry. The name of the process underwriting this window is "Python" (according to the Activity Monitor). Looking good so far.

The problem arises when I try to close the window containing the rendering. The window doesn't close; instead the process stops responding and I'm hit with the rainbow spinning wheel, causing me to force quit the application from the Activity Monitor. This happens every time I run the program on Jupyter lab.

However, it's worth noting that this problem is absent when I run the same lines of code with Visual Studio Code, which I'm taking to mean there's something funky with Open3D's integration with Jupyter. In VSCode, I still get the "Cocoa: Failed to find service port for display" error, but I am able to close the render window no problem.

Steps to reproduce the bug

import numpy as np
import open3d as o3d
temp = o3d.io.read_triangle_mesh('test_sphere.stl')
print(temp)
o3d.visualization.draw_geometries([temp])

Error message

[Open3D WARNING] GLFW Error: Cocoa: Failed to find service port for display

Expected behavior

• Render window closes

Additionally, I tried to run one of the jupyter examples (just to see if it's my code or something like an installation issue). I ran the following: `# import open3d as o3d from open3d.web_visualizer import draw

cube_red = o3d.geometry.TriangleMesh.create_box(1, 2, 4) cube_red.compute_vertex_normals() cube_red.paint_uniform_color((1.0, 0.0, 0.0)) draw(cube_red)

cube_blue = o3d.geometry.TriangleMesh.create_box(1, 2, 4) cube_blue.compute_vertex_normals() cube_blue.paint_uniform_color((0.0, 0.0, 1.0)) draw(cube_blue)`

And got the error: `--------------------------------------------------------------------------- RuntimeError Traceback (most recent call last) /var/folders/5f/1dm3w4px4b3cvb1gz1gfkx5w0000gn/T/ipykernel_12177/3961190166.py in 1 # import open3d as o3d ----> 2 from open3d.web_visualizer import draw 3 4 cube_red = o3d.geometry.TriangleMesh.create_box(1, 2, 4) 5 cube_red.compute_vertex_normals()

The error actually continues indefinitely and causes Jupyter lab to become unresponsive, forcing me to close it and kill the kernel from terminal. An image of the error output is also attached. I suspect these two issues are connected.

Same issue. When I use jupyter-notebook, run this code-"o3d.visualization.draw_geometries([mesh])", the window will open normally, but when I press 'Q' or close the window, the window will be freeze, I must force quit.
