Hello @JMiddey

1. KeyError: 'eth_usd_price_feed', be sure you have it correctly added to your brownie-config.yaml. Look for any typo or identartion error, also you should add it for each network you are working with.
2. brownie.network.connect(CONFIG.argv["network"]) the second error might be also due to a typo on your brownie-config, regarding to the networks.

hey was a solution to this issue ever found? i am having the exact same error

I did further research on this and it seems python 3.10.1 is giving troubles with this, so is recommended to use better 3.8
