                break;
        }
    }

    protected override void ChangeCurrentAnimation()
    {
        if(GetCurrentEnemyState == EnemyStates.Charger_Idle)
        {
            anim.speed = 1;
        }

        if (GetCurrentEnemyState == EnemyStates.Charger_Charge)
        {
            anim.speed = chargeSpeedMultiplier;
        }
    }
}

My charger enemy cannot walk, but it can charge when the Player is in front of it

The issue is probably because your currentEnemyState property is not updating correctly.

Do you know how to enter Debug Mode on the Inspector? You can select your enemy in Debug Mode on the Inspector, and it will expose all private variables on the component as well. Once done, you can look at the currentEnemyState property and see if it is updating correctly as your enemy is going about its business.
