Import cv2 Import error : module not found

Hi, I am new to Anaconda and Opencv. This is my first installation on Windows 11.
Using Anaconda3-2024.02-1-Windows-x86_64 .exe the installation to the default folder completed normally without adding Anaconda3 to my PATH environment variable, and updated to
Anaconda 2.6.0,
Then, I installed libopencv, opencv,py-opencv in base environment through Anaconda.Navigator.Evironments . I believe the Opencv is installed normally.
But, with Jupyter Notebook
"Import cv2 " makes “ImportError: DLL load failed while importing cv2: The specified module could not be found.”
Results using Spyder or Powrshell prompt are same.
"conda install opencv " makes message “# All requested packages already installed.” as expected.
What is my mistale?

OS : Windows11 Pro version 24H2 (Developer Mode : On)
