Could you tell me what version of pydantic you have on your computer?
It seems like the issue is that frozen is a beta release for now. But it is necessary for use in lumibot. You will need the latest version of pydantic either on your computer or in your virtual environment. So it depends on how you are set up.
Try installing pip install pydantic --upgrade to get to the latest version.
pydantic has been removed from lumibot
