Stuck because of KeyError: 'evm'

[TheoremaLC]

In the web3 section of Patrick Collin's Solidity course I got stuck because of this annoying and hard to explain error when compiling the deploy.py file. Here's the code (the same as everyone's doing this tutorial):

from solcx import compile_standard, install_solc
import json

install_solc("0.6.0")
with open("./SimpleStorage.sol", "r") as file:
    simple_storage_file = file.read()

# compile our solidity
install_solc("0.6.0")
compiled_sol = compile_standard(
    {
        "language": "Solidity",
        "sources": {"SimpleStorage.sol": {"content": simple_storage_file}},
        "settings": { "outputSelection": {
                "*": {
                    "*": ["abi", "metadata", "evm.bytecode", "evm.bytecode.sourceMap"]}
                }
            },
    },
)
with open("compiled_code.json", "w") as file:
    json.dump(compiled_sol, file)

# get bytecode
bytecode = compiled_sol["contracts"]["SimpleStorage.sol"]["evm"]["bytecode"]["object"]

# get abi
abi = compiled_sol["contracts"]["SimpleStorage.sol"]["SimpleStorage"]["abi"]
print(abi)

My compiled json:
