Visual Studio Code Can't debug Python program

Question

Recently ,My Visual Studios Code can't run in "Start Debugging" ,but it can run in "Run Without Debugging" .

The error message show it can't find the _thread module . The _thread module is in Python3 , I think the debugging mode using the Python3 configuration ,but I can't find where I can setting the debugging configuration

How should I do any setting to make my debugging can work ?

Below is my error message:

You need to select a python version on vscode. It looks like is taking the default Python version of your local machine. So you need to install a virutalenv that contains a different python version and that doesn't cause any conflicts with your Pythons local installation — EnriqueBet

@linlowa Have you had any problems with debugging before? After reading the contents of your two files, I feel that it is not the problem of the configuration file — MingJie-MSFT

Try the following:

Click cmd + shift + p and search for Python: select interpreter. Then select the correct one

https://code.visualstudio.com/docs/python/environments#_select-and-activate-an-environment

Set global default interpreter to python3 or python3.x in settings:

Making a new folder/workspace, and debug a test script. Make sure this new folder is not a virtual environment, to test if venv is the issue.
