Installing a game via GitHub onto Google Colab

Question

I am trying to install a python game I am working on onto Google Colab, via GitHub. It has been working fine for the past few weeks, but today I got this error, even though I didn't change anything. Any ideas, please?

The code I run:

# Install
!git clone --depth 1 --branch master https://github.com/Nokkla/AIDungeonClone
%cd AIDungeonClone/
!./install.sh
from IPython.display import clear_output
#clear_output()
#print("Installation Complete!")

Output:
