scenes.py InitialDemo won't work - Errno 13

Hi there,

Per the title, I can't get scenes.py InitialDemo to work. Here is my the terminal output:

```python

I'm running Ubuntu 20.04, Python 3.9, all dependencies installed. ```simulations.py``` runs fine. I downloaded the repository and am running the code from documents/videos-master/_2022/wordle - in this directory is ```custom```, ```data```,```__pycache__```, ```custom_config.yml```,```footnote.py```,```manim_imports_ext.yml```,```scenes.py``` and ```simulations.py```. Both .py files have the ```import sys sys.path.append...``` fix. Any insight into what I need to do to fix this would be mighty appreciated!
