wait_for_tstate_lock: ENGINE Waiting for thread Thread-4

[calambchops]

Hi,

On mac, my console is getting stuck at "ENGINE Waiting for thread Thread-4," and traceback shows it's stuck on tstate_lock which I'm not very familiar with. Running on my windows machine (python 3.8 installed) gives the same console output, but it will get stuck on "ENGINE Waiting for thread Thread-5," there's no traceback, and I'm unable to stop the program with keyboard interrupt.

I followed this tutorial: https://www.kdnuggets.com/2020/02/using-fitbit-web-api-python.html, and saw that someone commented having the same issue, but there's no resolution there yet. Any help would be appreciated.
