Closing tag </span> not found 209:76

Hello author @dcollien , how can I solve the following problem: When I try to filter HTML content, I always get an error: tag /.... not found. The code is as follows:

import pandas as pd
import FilterHTML
import requests
from bs4 import BeautifulSoup

读取CSV文件

df = pd.read_csv('xxxx.csv')

attributes = df.columns.tolist()
html_text = df.iloc[0]['crawl_html']
URL = df.iloc[0]['url']

headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36',
'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,/;q=0.8',
'Accept-Language': 'en-US,en;q=0.5',
'Connection': 'keep-alive',
'Upgrade-Insecure-Requests': '1'
}

response = requests.get(
URL,
headers=headers,
timeout=10,
# proxies={"http": None, "https": None}
)
response.raise_for_status()
html_content = response.text

soup = BeautifulSoup(html_content, 'html5lib')
fixed_html = str(soup)

try:

whitelist = {
            'a': {
                'href': 'url',
                'target': [
                    '_blank',
                    '_self'
                ],
                'class': [
                    'button'
                ]
            },
            'img': {
                'src': 'url',
                'width': 'measurement',
                'height': 'measurement'
            },
            'span': {
                'style': {
                    'color': 'color',
                    'background-color': 'color'
                }
            }
        }
filtered_html = FilterHTML.filter_html(fixed_html, spec=whitelist)
print(filtered_html)

except Exception as e:
raise Exception(f"下载网页失败: {e}")

Please provide some example HTML input ( the value of fixed_html) so the issue can be replicated
