text: Title: TypeError("unsupported operand type(s) for -: 'str' and 'int'") when downloading price data
  Body: The ```yf.download``` method does not seem to be working as of late for me, it gives me the error: ```TypeError("unsupported operand type(s) for -: 'str' and 'int'")``` when download stock data with ``period='max'`` or with ``start`` and ``end`` parameters.

  To prove this was not an error on my end, I followed the example in the documentation:
  ![image](https://user-images.githubusercontent.com/107745404/232230323-c1de53a3-44ce-4579-a3c2-0cb786f8d870.png)

  And here was the output (imported yfinance as yf):
  ```

  Has anyone else been experiencing this issue? Is this a problem on yfinance's end? How can this be resolved?
  
  Thanks
