Description

I'm aware Python 3.12 is not supported according to the trove classifiers, but I hope it will be soon. We're seeing the following exception many times during testing on Python 3.12.1, the tests run fine on 3.11.7.

Exception ignored in: <function tqdm.__del__ at 0x7ffff64a2c00>
Traceback (most recent call last):
