코드

def check_password(passwd, hashed):
    decoded_hashed = base64.b64decode(hashed)
    return bcrypt.checkpw(passwd.encode(), decoded_hashed)

수정 후 코드

# 비밀번호 검증 함수
def check_password(passwd, hashed):
    return bcrypt.checkpw(passwd.encode(), hashed.encode())

Base64 인코딩이 필요 없이 해시를 문자열로 처리하고, 검증할 때도 문자열 그대로 bcrypt.checkpw를 사용하니 오류 해결
