   Hm, I've only been testing it with the 3.0 beta. You might try installing that. It is a pre release. If you aren't familiar with installing pre-releases on pypi give me a shout.

   If you go to pypi for arcade:
   https://pypi.org/project/arcade/#history
   You can see the latest pre-release version is 3.0.0.dev21

   That can be installed with "pip install arcade==3.0.0.dev21"

   What are you using for a development environment? Are you using a venv (virtual environment)?

   I'm on the road for a few more days so I can't give detailed answers as I have no computer in front of me.

   Oh, it worked for the initial error! I started using venv and it solved the problem.

   Still, I am getting some errors...
   When It is running the moving arcade sprites it crashes and outputs the following error:
