If you're having zombie chrome processes using selenium, it could be due to failing to quit selenium when uncaught exceptions occur.

Use python "context manager" to ensure selenium quits/exits properly

with Scraper() as s:
    s.fetch()
 
class Scraper:
    def __init__(self):
        self.driver = get_chromedriver()
 
    def fetch(self):
        pass
 
    def __enter__(self):
        return self
 
    def __exit__(self, *exc):
        if self.driver:
            self.driver.quit()
