[🐛 Bug]: WebDriver "len(value) == 1" error

[toom-tym]

Description

WebDriver cannot be used
when running any code that uses webdriver, an error appears.
.../errorhandler.py", line 168, in check_response
if len(value) == 1:
^^^^^^^^^^
TypeError: object of type 'int' has no len()
the injury occurred spontaneously, after I had not used selenium for 30-40 days.
it does not depend on the code, any program that I make creates such an error.
at first I tried it on the old version, then I upgraded to the new one. the error did not go away.
it happens in any kind of webdriver usage, when connecting to the browser via debug port or when just launching any browser

Reproducible Code

from selenium import webdriver
driver = webdriver.Chrome()
driver.get('https://example.com/')
driver.quit()

Hi @TOOM-susy, webdriver_manager is not officially supported by selenium. Please let selenium manager fetch the driver.

@TOOM-susy the full error you provided doesn't match the error in your issue description?

Please remove webdriver_manager and try your code again. Also, please provide all of the information in the issue template.

@cgoldberg
from selenium import webdriver
driver = webdriver.Chrome()
driver.get('https://example.com/')
driver.quit()
has the same problem with webdriver it happens in any kind of webdriver usage, when connecting to the browser via debug port or when just launching any browser
I added the full error because I'm not quite sure if that's the case or if I missed something
