Massive amount of message about omni.ui

I create an extension with omni.ui.
It runs OK in USD Composer 2022.3.3.
But in 2023.1.1, it generate amount of message as following.

2023-09-01 02:10:22 [Info] [carb] Plugin omni.ui is already a dependency of omni.ui.glyphmanager.plugin; not changing unload order

And the following is imported module.

from pxr import Usd, UsdGeom, UsdSkel, Gf, Tf

import omni.ext
from omni.ui import color as cl
from omni.ui import scene as sc
import omni.ui as ui
import omni.kit
import omni.kit.viewport.utility
import carb

import inspect
import time
import os
import numpy as np
import math

And, an error occurred when enbaled in Create XR

Error: cannot import name ‘scene’ from ‘omni.ui’

How to resolve it.
Best regards.
