Don't work on Windows (window with the animation seems blank)

[foxypiratecove37350]

Describe the error

When I try to use on Windows, it seems work at the begining, but when the window with normaly the animation opens, this window is just blank, with nothing. I tested with manimgl example_scenes.py OpeningManimExample and the code from the tutorial in the docs (Quick Start - manim documentation), the same. I also tried with the flag -o to make an output, and the output seems empty.

Code and Error

Code:
The example_scenes.py file, then this code from the docs:

from manimlib import *

class SquareToCircle(Scene):
    def construct(self):
        circle = Circle()
        circle.set_fill(BLUE, opacity=0.5)
        circle.set_stroke(BLUE_E, width=4)
        square = Square()

        self.play(ShowCreation(square))
        self.wait()
        self.play(ReplacementTransform(square, circle))
        self.wait()

Error:
Firstly, I tried only the command in the README.md and I had this error:

So I set temporary_storage to the value of %temp%: C:/Users/user/AppData/Local/Temp, and now I have only this error:

这个问题我也遇到过，可能是您电脑硬件GPU设置问题，opengl 无法使用你的gpu 渲染. 你可以按照下面的步骤试试

一， 如果你是windows 请 进入 设置：

二， 把你的 python.exe 添加到 可以使用 gpu

三，进行下面的设置

不出意外就行了

@tianmaoyu Can you use english screenshots please? I don't speak chinese so it's complicated.

[tianmaoyu]

@foxypiratecove37350

Then add your python.exe to it.
