Timeout Exception fails when trying to call it Selenium

Question

I'm trying intentionally to locate wrong element so that I can call TimeoutException, and then call the function again, but instead I see the error stacktrace and it doesn't work.

Code:

def open_browser_func():
    global driver
    driver = webdriver.Chrome(service=ser)
    
    wait = WebDriverWait(driver, 20)

    driver.get("https://twitter.com/i/flow/login")
    print("Opening login page")

    try:
        def sign_in_acc():
            loginuser  = wait.until(EC.visibility_of_element_located((By.NAME, "textt")))
            loginuser.send_keys("Username", Keys.RETURN)

        sign_in_acc_timer = threading.Timer(5, sign_in_acc)
        sign_in_acc_timer.start()

    except TimeoutException:
        print("Username input crashed. Retrying now...")

        def retry_sign_in():
            driver.quit()
            return open_browser_func()
        retrytimer = threading.Timer(5, retry_sign_in)
        retrytimer.start()

    return driver

Error:

  File "C:\Users\Cassano\AppData\Roaming\Python\Python38\site-packages\selenium\webdriver\support\wait.py", line 89, in until
    raise TimeoutException(message, screen, stacktrace)

All I see is the TimeoutException in log, but not what I intend to call to handle it. What seems to be wrong?

Do you see the TimeoutException after Username is keyed in? Or even before that? — undetected Selenium

After the Explicit wait. EDIT: Figured it out, thanks nevertheless. — Cassano

You are waiting for element in different thread. As soon as you call sign_in_acc_timer.start() you start parallel thread where waiting is being executed and your open_browser_func() finishes. If you want to catch exceptions in child thread it is probably worth reading Catch a thread's exception in the caller thread?
