Error running Isaac Sim hello world example

I am running the example in this link 1. Hello World — Omniverse Robotics documentation

#launch Isaac Sim before any other imports
#default first two lines in any standalone application
from omni.isaac.kit import SimulationApp
simulation_app = SimulationApp({"headless": False}) # we can also run as headless.

from omni.isaac.core import World
from omni.isaac.core.objects import DynamicCuboid
import numpy as np

world = World()
fancy_cube =  world.scene.add(
        position=np.array([0, 0, 1.0]),
        scale=np.array([0.5015, 0.5015, 0.5015]),
        color=np.array([0, 0, 1.0]),
# Resetting the world needs to be called before querying anything related to an articulation specifically.
# Its recommended to always do a reset after adding your assets, for physics handles to be propagated properly
for i in range(500):
    position, orientation = fancy_cube.get_world_pose()
    linear_velocity = fancy_cube.get_linear_velocity()
    # will be shown on terminal
    print("Cube position is : " + str(position))
    print("Cube's orientation is : " + str(orientation))
    print("Cube's linear velocity is : " + str(linear_velocity))
    # we have control over stepping physics and rendering in this workflow
    # things run in sync
    world.step(render=True) # execute one physics step and one rendering step

simulation_app.close() # close Isaac Sim

I get the error below. Why am I getting this error?


closing and opening Isaac Sim resolved the issue.
