Do-While Loop Error - Not Repeating Play Again Game

I am facing with an issue where if a user want to play the game again, it will not prompt the user to key in the numbers, instead, it would print out statements and I am wondering why is doing that... It works perfectly fine if a user types in "No" and the game will end. I will provide a picture down so you can have a better understanding of what my issue is.

 import java.util.Scanner; 
import java.util.*;
public class Moropinzee

  public static void main(String[] args)
   {
  int Monkey = 1;
  int Robot = 2;
  int Pirate = 3;
  int Ninja = 4;
  int Zombie = 5;
  int player1 = 0;
  int player2 = 0;
  String answer;     

  Scanner scan = new Scanner(System.in);  

  System.out.print("Hey, let's play Moropinzee!\n" + 
              "Please enter a move.\n"); 

  do{              
  System.out.println("Player 1: Enter a number 1-5 for Monkey, Robot, Pirate, Ninja, or Zombie:");   

    while(!(player1>0) || !(player1<6))    
    {       
    player1 = scan.nextInt();       
    if(player1>=6)
    System.out.println("Invalid choice, Player 1. Enter a number 1-5:");              
    }  


    Scanner keyboard = new Scanner(System.in);
