Can't register user with Devise

Question

I have model User and two controllers for manage users:

1. Devise (without changes) - user can register and log in through Devise. Authorization works without problems,but registration does not work. Also the user cannot delete his account.
2. admin_users controller - user management through the admin panel. Here everything works flawlessly, except for deleting the user.

Devise controller is original admin_users_controller

class Admin::UsersController < ApplicationController
  layout "admin_application"

  before_action :set_user, only: [:show, :edit, :update, :destroy]

  def index
    @users = User.where.not(:id => current_user.id).order("id ASC")
    #authorize @users
  end

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

  def new
    @user = User.new
    #authorize @user
  end

  def create
    @user = User.new(user_params)
    #authorize @user
    if @user.save
      flash[:notice] = "Successfully created User."
      redirect_to admin_users_path
    else
      render :action => 'new'
    end
  end

  def edit
    @user = User.find(params[:id])
    #authorize @user
  end

  def update
    @user = User.find(params[:id])
    #authorize @user
    params[:user].delete(:password) if params[:user][:password].blank?
    params[:user].delete(:password_confirmation) if params[:user][:password].blank? and params[:user][:password_confirmation].blank?

    if @user.update(user_params)
      flash[:notice] = "Successfully updated User."
      redirect_to admin_users_path
    else
      render :action => 'edit'
    end
  end

  def destroy
      @user = User.find(params[:id])
      @user.destroy
      redirect_to admin_users_path
  end

  private

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

  def user_params
     params.require(:user).permit(:avatar, :first_name, :middle_name, :last_name, :username, :email, :role_id, :birth_date, :password, :password_confirmation)
  end
end

ApplicationController class ApplicationController < ActionController::Base protect_from_forgery with: :exception include Pundit # Pundit authorisation

  add_flash_types :success, :danger, :info

  before_action :authenticate_user! # All users must be logged in redirect to lgin page

  before_action :configure_permitted_parameters, if: :devise_controller?

  protected
    def configure_permitted_parameters
      devise_parameter_sanitizer.permit(:sign_up, keys: [:avatar])
      devise_parameter_sanitizer.permit(:account_update, keys: [:avatar, :first_name, :middle_name, :last_name, :username, :birth_date])
    end
end

Links to delete in views

= link_to "Delete", user_path(current_user), data: { confirm: "Are you sure?" }, method: :delete, :class => "btn btn-danger"

and

= link_to "Delete", admin_user_path(@user), data: { confirm: "Are you sure?" }, method: :delete, :class => "btn btn-danger"

Console log when Devise registration:
