Selenium error(DevToolsActivePort 文件不存在)

Question

我正在为网站编写测试，早些时候脚本运行没有问题，但过了一段时间后发生了错误- DevToolsActivePort文件不存在"，我试图通过添加- ">options.add_argument("——remote-debugging-port=9222")来修复。"，添加后我得到错误">chrome不可达". .尝试了不同的选项，但没有帮助。

from selenium import webdriver
# options
options = webdriver.ChromeOptions()
options.add_argument("--no-sandbox")
options.add_argument("user-agent=Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:84.0) Gecko/20100101 Firefox/84.0")
options.add_argument("--disable-blink-features=AutomationControlled")
options.add_argument("--remote-debugging-port=9222")
options.headless = True
driver = webdriver.Chrome(
    executable_path="/home/adfs_bot/chromedriver",
    options=options
)
driver.get('https://google.com/')

错误:
