Keep showing 'Rendering file' error

The code below shall be fine.

from manim import *

class NameOfAnimation(Scene):
def construct(self):

    plane = NumberPlane(
        x_range=[-7, 7, 1],
        y_range=[-4, 4, 1],
        background_line_style={
            "stroke_color": WHITE,
            "stroke_width": 2,
            "stroke_opacity": 0.3
        }
    )
    
    plane.add_coordinates()
    
    self.add(plane)

    box = Rectangle(
        stroke_color=GREEN_C, 
        stroke_opacity=0.7,
        fill_color=RED_B, 
        fill_opacity=0.5, 
        height=1, 
        width=1
    )

    self.add(box)
    
    self.play(box.animate.shift(RIGHT * 2), run_time=2)
    self.play(box.animate.shift(UP * 3), run_time=2)
    self.play(box.animate.shift(DOWN * 5 + LEFT * 5), run_time=2)
    self.play(box.animate.shift(UP * 1.5 + RIGHT * 1), run_time=2)

But still the moving square does not show in the video.

My steps are:
Firstly run the code by clicking the triangle on the top right hand side.
Then the manim sideview (the green circle).
Finally the button of "Render a New Scene" in the frame of manimsideview on the right.

Could anyone suggest the actions I shall do to solve the problem? Thank you.

a) you should include all your code between the three backticks `` ` of the template

b) I would personally advise against using Manim Sideview - it only complicates things. Writing
manim -pql kk.py NameOfAnimation just on the terminal would do the same and you can re-call the same command again simply with the up-cursor key

c) have a look at your error message. It tells you that there is something wrong with the partial_movie_file_list.txt where Manim stores information about the partial files it creates before assembling the final video. I would suggest to try to delete this file and possibly the complete folder with partial movie files and re-run the script.

Thanks for the reply, I will also try the method in this community for downloading manim and the consequent tutorials if any.

You don't need to download Manim - as you seem to already have a somewhat working installation...
