Visual Studio Code – Running Manim work in PyCharm but not in VSCode

I was installing Manim by following this guide Manim on Windows and when I ran the quickstart code it didn’t work

from manim import *


class CreateCircle(Scene):
    def construct(self):
        circle = Circle()  # create a circle
        circle.set_fill(PINK, opacity=0.5)  # set the color and transparency
        self.play(Create(circle))  # show the circle on screen

I executed py -m manim project.py CreateCircle on VSCode and it returned Manim could not find ffmpeg, which is required for generating video output. whereas I already installed ffmpeg.

After some research, I found that the IDE could cause problems like this but there was not much informations to solve my problem.
So I went on PyCharm and run the exact same file with the same command and it worked and the video was rendered (miraculously?).

So my questions are why it does not work on VSCode and how I could fix that ?
