VScode Extension Code Runner not working/error (python) when I run program

When I installed the code runner extension and I can't run the python program this error popped up:

When I turned off the extension the code run normally, but when I turned on the error pop up. Thank you for reading my problem! ( •̀ ω •́ )✧

What means "turn off the extension its working normal". According to the error report, this should be a problem with your Python environment variable setting. Have you tried the way named "Run Python File"? This is a function in extension pylance.

By the way, You should have installed the python extension.

updates:

You can use this option to run your python file. This is the file running option officially provided by Microsoft.
