TypeError: I am a bozo and can't debug this typeerror [closed]

I am receiving this error while running my code and can't seem to locate where the error is occurring and what to do about it. Also something to note is that the IDE I am using is not telling me where the error is occurring, just that it is occurring. "TypeError: cannot unpack non-iterable NoneType object"

Here is my code:

import random

def roll_dice():
    return random.randint(1, 6), random.randint(1, 6)


def computer_turn(game_score, goal):
    turn_score = 0

    while turn_score < goal:
        (d1, d2) = roll_dice()

        if d1 == 1 and d2 == 1:
            game_score = 0
            turn_score = 0
            break
        elif d1 == 1 or d2 == 1:
            turn_score = 0
            break
        else:
            turn_score += d1 + d2
            print(f"Computer rolled {d1}, {d2} Turn total {turn_score}")
    game_score += turn_score
    return game_score


def human_turn(game_score):
    turn_score = 0

    while True:
        d1, d2 = roll_dice()
        print(f"You rolled {d1}, {d2} Turn total: {turn_score}")
        roll_again = input("Roll again (y/n)? ").lower()

        if roll_again == 'n':
            game_score += turn_score
            break
        elif d1 == 1 or d2 == 1:
            break
        else:
            turn_score += d1 + d2
    return game_score


def computer_solo(goal):
    total_turns = 0
    game_score = 0

    while game_score < 100:
        game_score = computer_turn(game_score, goal)
        total_turns += 1
        print(f'Turns: {total_turns} Score: {game_score}')
    print(f'Turns: {total_turns}')
    return total_turns


def world_championship(games, goal_1, goal_2):
    player1_w = 0
    player2_w = 0
    total_games = 0

    while total_games < games:
        player1_score = computer_solo(goal_1)
        player2_score = computer_solo(goal_2)

        if player1_score > player2_score:
            player1_w += 1
        elif player2_score > player1_score:
            player2_w += 1

        total_games += 1

        print(f'Player 1: {player1_score} Player 2: {player2_score}')
        print(f'Player 1 Wins: {player1_w} Player 2 Wins: {player2_w}')


def human_vs_computer():
    human_score = 0
    computer_score = 0

    while human_score < 100 and computer_score < 100:
        human_score = human_turn(human_score)
        print(f'You: {human_score} Computer: {computer_score}')

        if human_score >= 100:
            print("Congratulations!")
            break

        computer_score = computer_turn(computer_score, 20)
        print(f'You: {human_score} Computer: {computer_score}')

        if computer_score >= 100:
            print("Congrats! You stink!")


if __name__ == '__main__':
    world_championship(7, 20, 20)

I've attempted to change various variables around but I can't find where the error is occurring and that makes it difficult
