Next time, please provide more information, be more clear, and would be better to attach some pictures. Otherwise, it's hard to understand what's your mean, and the people hard to give you suitable suggestions.

I guess the problem you meet just because you run your code with a different environment. The environment which you run across the problem because you haven't installed the 'dotenv' package. It looks like you had installed the package in your global python environment, but you haven't installed the package in your virtual environment. You can add this code in your python file to distinguish which python, which environment you are using:

import sys
print(sys.executable)

If I am right, then you just need to activate your virtual environment(Ctrl+Shift+`), and run the command "pip install dotenv". Before install, you should check which pip you are using, through the command "pip --version". Be sure you had installed the package into your virtual environment.
