My Windows PC VSCode is the latest version 1.103, and currently there are the following issues:
4.After opening the Python file, the Python interpreter has also been selected, but it takes a long time for the syntax in the Python file to be highlighted
The plugin I installed in VSCode is: CodeGeeX、Jupyter、Jupyter Cell Tags、Jupyter Keymap、Jupyter Notebook Rendeners、Jupyter Slide Show、Pylance、Python、Python Debugger、Python Environments
Please help me analyze the causes of these problems and provide solutions (I have tried uninstalling and reinstalling VSCode, but still have these issues)
