可能是因为没有找到对应的标签，您可以尝试修改代码，查看是否可以成功获取名称：

import requests 
from bs4 import BeautifulSoup 

url = 'https://weibo.com/u/1670659923' 
headers = { 
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36 Edg/114.0.1823.41' 
} 
cookies = { 
    'SUB': '_2A25JhpdQDeRhGeBM61MQ8CjOzzqIHXVq9Y-YrDV8PUNbmtAGLWvxkW9NRQ-ugE6rVY1cMvmezl4YyGeJ1ClvO4dN', 
    'SUBP': '0033WrSXqPxfM725Ws9jqgMF55529P9D9Wh2o78rH.vjBjZo6khos3mY5JpX5KzhUgL.FoqEeh2pehqEShq2dJLoIpjLxK.L1h2LB--LxKBLBonL12BLxKnL1hzL1h.t;'             
    'ALF=1717836416; SSOLoginState=1686300416;_s_tentry=weibo.com;MLOGIN=1;XSRF-TOKEN=LdwKRX-Gczu2_lX9TQQ4O9EY' 
} 
response = requests.get(url, headers=headers,cookies=cookies) 
soup = BeautifulSoup(response.text, 'html.parser') 

# 获取名称 
name = soup.find('h1', {'class': 'username'}) 
if name:
    print(name.text.strip())
else:
    print("未找到对应的标签！")

在这里，我将查找的标签从`div`改为了`h1`，并且将该标签的class从`detail_wbtext_4CRf9`改为了`username`，这是因为可能页面的结构或者样式发生了改变。同时，我添加了一个判断语句，如果没有找到对应的标签，则输出一个提示信息。
