Selenium does not react on alert

Chrome version: 80.0.3987.149 Selenium version: 3.141.0

The idea behind program is to open new window with video, collect information from confirmation box (automatically appears when window is opened) and accept the confirmation. Problem is that program hangs when new window appears.

try:
    browser.find_element_by_xpath("//*[contains(text(), 'VOD')]").click()
except NoSuchElementException:
    continue

main_handle = browser.current_window_handle

for handle in browser.window_handles:
    if handle != main_handle:
        browser.switch_to.window(handle)
        print('I switched to: %s' % (browser.current_window_handle)) # this line is not printed

try:
    WebDriverWait(browser, 3).until(EC.alert_is_present())
    alert = browser.switch_to.alert
    alert_text = alert.text
    alert.accept()
except Exception as e:
    print('Exception: ', e)
