What I have tried:

1. Reboot the system. Done but nothing happens.

2. Uninstall the pylance and python extension. Done but nothing happens.

3. Install vscode insider and open the same jupyter notebook file. Done but the same issue still occurs.

4. Switch different conda virtual environments. Done but the same issue still occurs.

UPDATE

Add a GitHub link:

select 2022.16.1 version

Restart vscode after installation is complete
