Why does the break statement not work while scraping reviews with Selenium and BeautifulSoup in Python?

I am scraping reviews with Selenium and BeautifulSoup in Python but the break statement does not work so that the while loop continues even after arriving at the last review page of a product. From what I understand it should work as there is no "next page" button on the last review page anymore. Can someone explain why break is not working?

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import time
import pandas as pd
from bs4 import BeautifulSoup

driver = webdriver.Chrome()

reviewlist= []

ASINs = ['B09SXL3HPG', 'B07TP8LLQZ']
for a in range(len(ASINs)):
    url = 'https://www.amazon.de/dp/' + str(ASINs[a])
    driver.get(url)

    #Accept cookies (only if you need it)
    if a == 0:
        accept_cookies = WebDriverWait(driver, 5).until(EC.presence_of_element_located((By.CSS_SELECTOR, "input[id='sp-cc-accept']"))).click()

    #Go to all reviews
    WebDriverWait(driver, 10).until(
        EC.element_to_be_clickable((By.CSS_SELECTOR, "a[data-hook='see-all-reviews-link-foot']"))).click()

    while True:
        soup = BeautifulSoup(driver.page_source, 'html.parser')
        reviews = soup.find_all('div', {'data-hook': 'review'})
        for item in reviews:
            review = {
                'date': item.find('span', {'data-hook': 'review-date'}).text.strip(),
                'body': item.find('span', {'data-hook': 'review-body'}).text.strip(),
                }
            reviewlist.append(review)

        try:
            next_page_button = WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.CSS_SELECTOR, '.a-pagination .a-last'))).click()
            print('click')
            time.sleep(1)
        except Exception as ex:
            print(ex,"!!!!!!!")
            break
