CfT >= 119 / Selenium 4.16 / Python 3.12 / webdriver.set_window_size(x,y) returns 500 response from webdriver; webdriver.get("url") does not actually navigate to the url

[rhynot-ryan]

Python 3.12
Selenium 4.16
W11P 23H2 (22631.2715)
with regular Chrome 120.0.6099.71 installed on machine

Issue exists with CfT >= 119, including CfT stable 120.0.6099.71
Issue does not exist with regular Chrome 120.0.6099.71 or CfT <= 118

calling webdriver.set_window_size(x,y) returns 500 response from webdriver and throws a WebDriverException
calling webdriver.get("url") does not actually navigate to the url though webdriver returns 200 response - the browser address bar displays just data:,; the url passed from webdriver.get("url") is not displayed and no page is rendered in the browser.

Example code:

from selenium import webdriver
import os
import logging

logger = logging.getLogger('selenium')
logger.setLevel(logging.DEBUG)
handler = logging.FileHandler(os.environ.get("HOMEDRIVE").replace("\\","/") + os.environ.get("HOMEPATH").replace("\\","/") + "/Desktop/testLog.txt")
logger.addHandler(handler)

browserOpts = webdriver.ChromeOptions()
browserOpts.browser_version = "120" #change this value to different versions
browserPrefs = {"credentials_enable_service": False,"profile.password_manager_enabled": False}
browserOpts.add_experimental_option("excludeSwitches", ["enable-automation","enable-logging"])
browserOpts.add_experimental_option("prefs", browserPrefs)
browserOpts.add_argument("--disable-single-click-autofill")
browserOpts.set_capability("goog:loggingPrefs", {"performance": "ALL"})
browser = webdriver.Chrome(options=browserOpts)
browser.get("https://www.google.com")
browser.set_window_size(1300,1000)

Debug log output when run with CfT 117 or 118 (browserOpts.browser_version = "117" or browserOpts.browser_version = "118") - works as expected:

browserOpts.browser_version = "canary" CfT 122.0.6170.0 - SAME PROBLEM - url does not load & resizing window throws exception

With regular/installed Chrome 120.0.6099.71:
browserOpts.browser_version = "stable" Chrome REGULAR 120.0.6099.71 - NO ISSUE

I renamed the directory of my installed regular Chrome and changed the relevant HKCU key so it wouldnt be found by Selenium Manager and force it to dowload CfT:
browserOpts.browser_version = "stable" CfT 120.0.6099.71 - SAME PROBLEM - url does not load & resizing window throws exception

So it appears that the issue is related to CfT version 119 and later as 'regular' Chrome 120 does not exhibit the issue but CfT >= 119 (thru 122 canary) DOES give the error.

Originally reported to SeleniumHQ (SeleniumHQ/selenium#13257) but after further troubleshooting and discovering the issue only affected CfT and not regular Chrome, was asked to report here.
