Things I checked to try diagnose:

• .env has valid Infura project id
• have 0.5 eth + 20 LINK in metamask account; should be more than enough. Only using like 0.01-0.025 eth and 0 LINK each time i run the (failed) script
• copy + pasted all of your relevant project files, so assume they're identical: Lottery.sol, LinkTokenInterface.sol, deploy_lottery.py, helpful_scripts.py, lottery_test_integration.py
• switched between your identical brownie-config.yaml file and one that i changed with updated addresses (updated as of 20th feb 2022)and ran the script with both configs Updated one: (including it, just in case)

Thank you for your time.

Rinkeby is being really slow and hard to verify right now. You might want to do something like this: https://github.com/smartcontractkit/chainlink-mix/blob/main/scripts/vrf_scripts/01_deploy_vrf.py

You wait X confirmations and then go for your verification.

Ah. Legend, thanks.
