My response here should clear things up, but let me know if you have any other questions or issues!

How can I downgrade from python 3.10 to python 3.8?

Hey @efibendor! I’m sorry that Ghostwriter gave you an incorrect response! You can change your Repl’s environment from Python 3.10 to Python 3.8 by using our Nix configuration. For example, you can use the Nix package python38 instead of the default Python package in the replit.nix file which should downgrade your environment to Python 3.8.
