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

Question

操作系统： Win10
Python： venv 3.8
铬： 95.0.4638.69
Chrome 驱动程序： 95.0.4638.69
硒： 4.0.0

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"libs\chromedriver.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)

测试在前一天工作，当我再次启动我的机器时出现错误：

普通 Python 代码执行正常。

删除并再次添加chromedriver.exe修复了问题。
