Answer 1

links = main_div.find_elements_by_class_name('my-matches-table-row-container')
count = 0
while(len(links)!=count):
    links = main_div.find_elements_by_class_name('my-matches-table-row-container')
    link=links[count]
    count+=1
    link.click()
    parent_window = driver.current_window_handle
    all_windows = driver.window_handles
    child_window = [window for window in all_windows if window != parent_window][0]
    driver.switch_to.window(child_window)
    time.sleep(13)
    error = driver.find_element_by_class_name('video-message')
    if error.text == 'No video to display.':
        break
    else:
        div1 = WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CLASS_NAME, 'vm-match-actions-directive')))
        divs2 = div1.find_elements_by_class_name('button-container')
        count2 = 0
        while(len(divs2)!=count2):
            divs2 = div1.find_elements_by_class_name('button-container')
            div=divs[count2] 
            count2+ =1
            if 'Video' and 'Download' in div.text:
                link = div.find_element_by_tag_name('a')
                actionChains.context_click(link)
                actionChains.perform()
                pyautogui.typewrite(['down', 'down', 'down', 'down', 'enter'])
                time.sleep(5)
                pyautogui.hotkey('enter')
                driver.refresh()
                time.sleep(15)
                try:
                    driver.find_element_by_xpath('//*[@id="portal-match-controls-column"]/div[3]/vm-match-actions/div/div/div[1]/div[4]/span[2]').click()
                    driver.find_element_by_xpath('//button[contains(text(),"I Accept")]').click()
                    time.sleep(4)
                    break
                except:
                    break
            else:
                continue
    driver.close()
    driver.switch_to.window(parent_window)

             

you should always find divs again , as you are clicking 'link' and this modifies the DOM, when ever DOM ( PAge html) is modified you have find all elements again as the previous reference is lost , this is why you get stale element

you can use driver.back() to navigate back
