You can fix this issue by putting the entire program into a try: except: block and running 1/0 to raise an error. Since the program is in the try: except: block, there will be no error message and the program will return and end.

Example:

try:
  while True:
    if input("Exit? ") == "yes":
      1/0
except:
  pass

Output:

Here's your fixed program: (I also removed some empty lines.)

try:
  import random

  deck = list('234567890JQKA')
  random.shuffle(deck)
  value = {'2':2, '3':3, '4':4, '5':5, '6':6, '7':7, '8':8,'9':9, '0':10, 'J':11, 'Q':12, 'K':13, 'A':1}
          
  player_win = 0
  player_losses = 0
  dealer_cards = []
  player_cards = []

  while len(dealer_cards) != 2:
    dealer_cards.append(random.randint(1,5))

    if len(dealer_cards) == 2:
      print("Dealer has X &", dealer_cards[1])

  while len(player_cards) != 2:
    player_cards.append(random.randint(1, 5))
    if len(player_cards) == 2:
      print('you have a total of:', sum(player_cards), 'from these cards:', player_cards)
      if sum(player_cards) == 21:
        print('you have 21 you got blackjack, well done:)') 
        1/0
        
    player = [deck.pop() for _ in range(2)]
    cpu = [deck.pop() for _ in range(2)]

  if sum(player_cards) < 21:
    
    action = input('do you want to hit or stay:')
      
    while action == 'hit':
      new_card = random.randint(1, 13)
      player_cards.append(new_card)
      if sum(player_cards) > 21:
        print('\n you bust, the dealer automatically wins', player_cards)
        1/0
      else:
        print("You now have a total of " + str(sum(player_cards)) + " from these cards", player_cards)
        action = input("Do you want to stay or hit? ")
    if action == 'stay':
      print('your total sum was:', sum(player_cards), '\n the dealer will play now')
      
  if sum(player_cards) == 21:
    print('you have 21 you got blackjack, well done:)')
    1/0

  def dealer_play():
    print("Dealer had a total of " + str(sum(dealer_cards)));
    while(sum(dealer_cards) < 17):
      dealer_cards.append(random.randint(1,13))
      print("Dealer's total is now " + str(sum(dealer_cards)));
      1/0
      if(sum(dealer_cards) > 21):
        print("Dealer bust, you win!," "dealer =", sum(dealer_cards), "player =", sum(player_cards))
        
    if sum(dealer_cards) == 21:
      print('the dealer got blackjack', sum(dealer_cards))
      1/0

  dealer_play()

  while sum(dealer_cards) < 21:
    if sum(dealer_cards) > sum(player_cards):
      print('you lost to the dealer' )
      1/0
    elif sum(dealer_cards) == sum(player_cards):
      print('you and the dealer tied', 'dealer =', sum(dealer_cards), 'player =', sum(player_cards))
      1/0

  while sum(player_cards) < 21:
    if sum(player_cards) > sum(dealer_cards):
    print('congratulations you won')
    1/0
except:
  pass
