Why is stale error selenium crashing?

Question

Python

def collectArticle(self, link: str) -> None:
        """
        Goes through the posts on the given page and saves 'em screenshots, which will later on be used.
        """
        time.sleep(.2)    

        self.driver.get(link)

        self.driver.execute_script("document.body.style.zoom='80%'")

        self.wait.until(EC.presence_of_all_elements_located((By.XPATH, searchConfig.facebook['properties']['articles'])))
        self.wait.until(EC.element_to_be_clickable((By.XPATH, '//div[@role="main"]')))
        self.wait.until(EC.presence_of_element_located((By.XPATH, '//div[@role="main"]')))
        self.wait.until(EC.visibility_of_element_located((By.XPATH, '//div[@role="main"]')))

        articles: List[WebElement] = self.driver.find_elements(By.XPATH, searchConfig.facebook['properties']['articles'])

        print(len(articles))

        for article in articles:
            try:
                time.sleep(2)
                self.ac.move_to_element_with_offset(article, 0, 100).perform()
                time.sleep(config.scrollTimePause)
                print(article)
                # self.takeScreenshot(article.screenshot_as_png, f'facebook{random.randint(1, 100)}.png')
            except sex.WebDriverException as e:
                print(e.msg)
                continue

Why is he getting a stail error? I am obviously waiting for this element, it is on the page, on the screen - too. I have even scattered time slips, you never know.
