BUG: ValueError: need at most 63 handles, got a sequence of length 66

Describe the bug Hi! I tried the MOOSE to segment CT on the Windows server with 32 cores. It outputs an error:

 🔮 PREDICT:

\ [1/1] Preparing data for prediction for S1...Exception in thread Thread-6 (_handle_workers):
Traceback (most recent call last):

I saw some people encountered similar issues before (https://github.com/psf/black/issues/564).

Is it possible to make some adjustments for this issue?

To Reproduce (moose-env) Z:\code>moosez -d Z:\20240719_CB467_idmoose\moose_out\moose_clin_ct_body -m clin_ct_body

Expected behavior It works for a Windows server with 8 cores. (same OS settings except for the spec)

@mprires @Keyn34 can you manage this - I have very little resources, to debug.

Hi @BruceZhang-624

Can you tell me which python version you are using? Also from your command line output it seems like you are using an anaconda environment. Did you try a python venv environment?
