Python Selenium测试:[WinError 193]%1不是有效的Win32应用程序

Question

OS:Win10
Python:venv3.8
铬：95.0.4638.69
铬驱动程序：95.0.4638.39
硒：14.0.0

尝试运行简单的测试：

import os
import unittest
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.common.by import By

class SmokeTests(unittest.TestCase):
@classmethod
def setUpClass(self):
chromedriver_path = os.path.join(os.path.dirname(os.path.realpath(__file__)), r"libschromedriver.exe")
ser = Service(chromedriver_path)
self.driver = webdriver.Chrome(service=ser)
base_url = 'https://google.com/'
self.driver.get(base_url)
@classmethod
def tearDownClass(self):
self.driver.quit()
def test_name_in_tab_title(self):
expected_tab_title = 'Google'
observed_tab_title = self.driver.title
self.assertEqual(expected_tab_title, observed_tab_title)

测试在前一天开始，当我再次启动我的机器时，我出现了错误：

普通Python代码执行正常。

删除并再次添加chromedriver.exe修复了问题。
