Aplicação não está fechando

Programação
#1

Boa tarde estou desenvolvendo uma aplicação só que ele não está fechando sempre que aperto no botão de fechar ela fecha e abre de novo. Quem puder ajudar agradeço esse é o código que estou fazendo:

import mediapipe as mp #Import mediapipe
import cv2 #Import opencv

mp_drawing = mp.solutions.drawing_utils #Desenhar utilitarios
mp_holistic = mp.solutions.holistic #Mediapipe soluções

cap = cv2.VideoCapture(0)

Initiate holistic model

with mp_holistic.Holistic(min_detection_confidence=0.5, min_tracking_confidence=0.5) as holistic:

while cap.isOpened():
    ret, frame = cap.read()
    
    # Recolor Feed
    image = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB)
    image.flags.writeable = False        
    
    # Make Detections
    results = holistic.process(image)
    # print(results.face_landmarks)
    
    # face_landmarks, pose_landmarks, left_hand_landmarks, right_hand_landmarks
    
    # Recolor image back to BGR for rendering
    image.flags.writeable = True   
    image = cv2.cvtColor(image, cv2.COLOR_RGB2BGR)
    
    # 1. Draw face landmarks
    mp_drawing.draw_landmarks(image, results.face_landmarks, mp_holistic.FACE_CONNECTIONS, 
                             mp_drawing.DrawingSpec(color=(80,110,10), thickness=1, circle_radius=1),
                             mp_drawing.DrawingSpec(color=(80,256,121), thickness=1, circle_radius=1)
                             )
    
    # 2. Right hand
    mp_drawing.draw_landmarks(image, results.right_hand_landmarks, mp_holistic.HAND_CONNECTIONS, 
                             mp_drawing.DrawingSpec(color=(80,22,10), thickness=2, circle_radius=4),
                             mp_drawing.DrawingSpec(color=(80,44,121), thickness=2, circle_radius=2)
                             )

    # 3. Left Hand
    mp_drawing.draw_landmarks(image, results.left_hand_landmarks, mp_holistic.HAND_CONNECTIONS, 
                             mp_drawing.DrawingSpec(color=(121,22,76), thickness=2, circle_radius=4),
                             mp_drawing.DrawingSpec(color=(121,44,250), thickness=2, circle_radius=2)
                             )

    # 4. Pose Detections
    mp_drawing.draw_landmarks(image, results.pose_landmarks, mp_holistic.POSE_CONNECTIONS, 
                             mp_drawing.DrawingSpec(color=(245,117,66), thickness=2, circle_radius=4),
                             mp_drawing.DrawingSpec(color=(245,66,230), thickness=2, circle_radius=2)
                             )
                    
    cv2.imshow('Raw Webcam Feed', image)

    if cv2.waitKey(10) & 0xFF == ord('q'):
        break

cap.release()
cv2.destroyAllWindows()
