Validation error: "Password can't be blank" but it isn't blank

It keeps saying that the password field and the password_confirmation field is blank, even when I use the rails console to create a new user. Also, the error message for the password confirmation repeats and I'm not sure why. Any help would be greatly appreciated.

Screenshot of error messages

User Model

class User < ApplicationRecord
  has_secure_password
  validates_confirmation_of :password
  attr_accessor :password
  validates :password, length: 6..100, confirmation: true
  validates :email, format: { with: /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\z/i, on: :create }
  before_save :encrypt_password
  validates_presence_of :password_confirmation, if: lambda {| u| u.password.present? }


  def encrypt_password
    self.password_salt = BCrypt::Engine.generate_salt
    self.password_hash = BCrypt::Engine.hash_secret(password,password_salt)

  end
end

User controller

  class UsersController < ApplicationController
  def new
    @user = User.new
  end

  def index
  end

  def show
    @user = User.find(params[:id])
  end

  def create
    @user = User.new(user_params)
    if @user.save and user.valid?
      session[:user_id] = @user.id
      render 'users/new'
    else
      render :action => "new"
    end
  end

  private
  def user_params
    params.required(:user).permit(:name, :email, :password, :password_confirmation)
  end
