파이썬 버전은 문제가 없으나 FinanceDataReader의 버전이 낮은 것을 쓰시는 것 같습니다. 현재는 investing이 아닌 yahoo finance에서 가져오고 있습니다. 다음과 같이 FinanceDataReader를 최신 버전으로 업데이트 하여 사용해 보시기 바랍니다.

pip install -U finance-datareader

다음과 같이 잘 동작하고 있습니다.

일시적인 문제인지 확인해봐 주시고,
계속 문제가 있으신 경우 에러 스택 전체를 알려주시면 감사합니다.

살펴봐 주셔서 고맙습니다.
잘 되던 코드가 갑자기 문제가 발생했습니다.
다른 라이브러리 설치과정에서 발생한 문제일 수 있지만요.
아래는 전체 에러 코드입니다.

참고로 finance-datareader 1.16.0과 Python 3.8.8을 사용하고 있습니다.

바쁘실텐데 답변 감사합니다.
저도 다른 곳에서 실행해보니 이상없이 가져오는 것을 확인했습니다.
제 개발 환경에 변화가 생겨 발생한 문제 같습니다.
