maximize_window() fails with Chrome 133+ in undetected-chromedriver

Issue Description

When using undetected-chromedriver with Chrome version 133 or higher, the maximize_window() method fails with a JavaScript evaluation error. This issue does not occur with Chrome version 131 or lower.

Importantly, this issue is specific to undetected-chromedriver - the same code works perfectly fine with regular ChromeDriver:

# Works fine with regular ChromeDriver
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument('--start-maximized')

driver = webdriver.Chrome(
    options=options
)
driver.maximize_window()  # Works without any issues

# Fails with undetected-chromedriver
import undetected_chromedriver as uc

options = uc.ChromeOptions()
options.add_argument('--start-maximized')

driver = uc.Chrome(
    headless=False,
    use_subprocess=False,
    version_main=134,  # Issue occurs with version 133+
    options=options
)
driver.maximize_window()  # Triggers the error

Environment

• undetected-chromedriver: 3.5.5
• Chrome version: 134.0.6998.3
• Python: 3.11
• OS: Ubuntu 22.04 (Docker)

Steps to Reproduce

1. Install undetected-chromedriver and set up Chrome 134
2. Run the example code above
3. The error occurs specifically with undetected-chromedriver, while regular ChromeDriver works normally

Error Message

selenium.common.exceptions.WebDriverException: Message: unknown error: JavaScript code failed
from unknown command: 'Runtime.evaluate' wasn't found
(Session info: chrome=134.0.6998.3)

Expected Behavior

• The browser window should maximize without any errors
• This functionality works correctly with:
  • Chrome version 131 in undetected-chromedriver
  • All Chrome versions in regular ChromeDriver

Additional Information

• The issue is exclusive to undetected-chromedriver (regular ChromeDriver works fine with all versions)
• The error occurs in both headless and non-headless modes
• Adding --start-maximized to ChromeOptions does not prevent the issue

Current Workaround

Using Chrome version 131 as a temporary solution:

driver = uc.Chrome(
    version_main=131,  # Using older version as workaround
    options=options
)

Please let me know if you need any additional information to investigate this issue.

I feel that not only maximize_window(), but also many of the driver.~ commands are not working properly. I would like to ask the developers of uc to address this issue as soon as possible.
