@jianboy Can you try with this version and see if you get this error: https://pvsc.blob.core.windows.net/extension-builds/ms-python-insiders.vsix ?

I had download and try it. this insiders plugin has no error.

All python version has error. I think it has nothing to do with the python version. python plugin has problem I test version :

v2020.7.96456           error
v2020.7.94776           error
v2020.6.89148           ok
v2020.5.80290           ok
vv2020.3.71113         ok

I can not install another verison from vscode directly. So I had to download from github.

By using the dichotomy, I can already locate the version that caused the problem
