Scraping a Flexible Element - works at first, and then crashes

[JonnyB]

import selenium
import os
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
import time

executable_path = "C:\Program Files (x86)\chromedriver.exe"
os.environ["webdriver.chrome.driver"] = executable_path

chrome_options = Options()
chrome_options.add_extension('C:\\Program Files (x86)\\adguard.crx')

driver = webdriver.Chrome(executable_path=executable_path, chrome_options=chrome_options)


driver.get("https://pinterest.com")

element = driver.find_element_by_xpath('//div[contains(text(),"Live Posts")]')
element.click()


time.sleep(6)
posts = driver.find_elements_by_class_name('_3MKTqZAzt9ZahG8uCIFoOb')

for post in posts:
		title = post.find_element_by_class_name('_1h0SwjHGr__FljITS6J2FA').text
		time_ago = post.find_element_by_class_name('_94ZmeYYiS8oR1zgGtS0xI').text	
		value= post.find_element_by_class_name('_1jlBA3TjmrUfFXXCyWbfpV').text
		print(title, value, time_ago)

This code works and scrapes the first several lines, but then it crashes with this error:

selenium.common.exceptions.StaleElementReferenceException: Message: stale element reference: element is not attached to the page document

The element I am trying to scrape is flex, and gets reloaded every dew seconds (at that time when it reloads, the script crashes. the reload takes less than 1 second.
This is image of the flex element:
