Data Export problem

Dear Team,
My data-downloading process relies on the Python API, which has been performing flawlessly. However, in the recent fortnight, I’ve encountered some unexpected error messages. To be precise, when executing my Python script, I encounter the following error.

Traceback (most recent call last):
File “FilePath\download_clinical_all.py”, line 3, in

File “FilePath\venv\lib\site-packages\ssaw_init_.py”, line 2, in

TypeError: issubclass() arg 1 must be a class

Please look into it.
