Unable to loop trough the links when crawling a website with Python and Selenium

Question

I want to crawl one website but I have a problem with looping trough page. I want to create a system that collects all links, then click on each link and collects data (date in this case). I wrote a code but I keep getting this error:

StaleElementReferenceException: Message: stale element reference: element is not attached to the page document
  (Session info: chrome=98.0.4758.109)

I have tried to increase the sleep interval but the result is the same. The error happens after on second iteration (after first link).

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import requests
import time

# url for crawling
url = "https://bstger.weblaw.ch/?size=n_60_n"
    
# path to selenium
path = 'path to selenium'
driver = webdriver.Chrome(path)
driver.get(url)
time.sleep(4)    
    
# click on search button
buttonClickSearch = driver.find_element_by_xpath('//*[@id="root"]/div/div/div[2]/div[1]/div/div[3]/form/div/input').click()
time.sleep(3)    
    
# get all links
all_links = driver.find_elements_by_tag_name('li.sui-result div.sui-result__header a')
print(all_links)
print()

# loop trough links and crawl them
for link in all_links:
    
    # click on link
    print(link)
    time.sleep(4)
    click = link.click() # I GET THE ERROR HERE ON SECOND ITERATION
    time.sleep(4)
        
    # get date
    date = driver.find_element_by_tag_name('div.filter-data button.wlclight13').text
    day = date.split('.')[0]
    month = date.split('.')[1]
    year = date.split('.')[2]
    date = year + "-" + month + "-" + day
    print(date)
    print()
    
    # click on back button
    back_button = driver.find_element_by_xpath('//*[@id="root"]/div/section[1]/div[1]/div[1]/a').click()
    time.sleep(4)
    #scroll
    driver.execute_script("window.scrollTo(0, 200)") 

Answer 1

As already mentioned clicking on Back button is unstable. But can use the Next button to navigate to other links.

And better to apply some Explicit waits.

driver.get("https://bstger.weblaw.ch/?size=n_60_n")

wait = WebDriverWait(driver,30)
actions = ActionChains(driver)

buttonClickSearch = wait.until(EC.element_to_be_clickable((By.XPATH,"//input[@aria-label='search button']")))
actions.move_to_element(buttonClickSearch).click()

time.sleep(5)
all_links = driver.find_elements(By.XPATH,"//div[@class='sui-result__header']/a")
all_links[0].click() # Click on the First link.

for i in range(20):
    ...
    next = wait.until(EC.element_to_be_clickable((By.XPATH,"//button[contains(@class,'next')]")))
    next.click() # Click on next link for 20 iterations.
