The exception you posted occurs when you call comments.click(). But in your code snippet you don't show how comments is defined. Please specify exactly what you are doing and what you want to achieve. — Misc08, Commented Feb 19, 2022 at 1:24
Selenium gives references to elements in browser memory - when you load new page then it removes elements from memory and when you go back to previous page then these elements can be in different place in memory and references are useless - and this gives your message "stale element reference: element is not attached to the page document". You have to use find_element again, or first you should get all URLS as text, next change pages and go back, and later use get(url) instead of click(). But when you have URLS then you don't have to go back but use directly get(url) — furas, Commented Feb 19, 2022 at 4:19

You need to search comments element again using find element once you returned to previous page I'm assuming after driver.back() you want to click on comment1 then your code should looks like

comment1 = driver.find_element(By.CSS_SELECTOR, '#app > div.tiktok-19fglm-DivBodyContainer.etsvyce0 > a')
comment1.click()
time.sleep(7)
try:
    follow = driver.find_element(By.CSS_SELECTOR, '#app > div.tiktok-ywuvyb-DivBodyContainer.etsvyce0 > div.tiktok-1h3j14u-DivFollowButtonWrapper.e143oaad4')
    follow.click()
    driver.back()
except:
    driver.back()
comment1 = driver.find_element(By.CSS_SELECTOR, '#app > div.tiktok-19fglm-DivBodyContainer.etsvyce0 > a')
comment1.click()
