Having exactly the same problem with
Selenium is not loading TikTok pages
There's nothing inside div class="jsx-1792501825 video-feed" tag, where originally the video informations are supposed to be located.
driver = webdriver.Chrome('chromedriver',options=options)
driver.get("https://www.tiktok.com/trending")
time.sleep(10)
driver.execute_script("scroll(0, 2500);")
video_feed = driver.find_element_by_css_selector('html > body > div > div > div > div > div > div > div > main')
print(video_feed.get_attribute('innerHTML'))
result
<div class="jsx-1792501825 video-feed"></div><div class="jsx-1970579021 jsx-1005258868 tiktok-loading feed-loading"></div>
