Is there an existing issue for this problem?

I have searched the existing issues

OrcaSlicer Version

2.3.1

Operating System (OS)

macOS

OS Version

Sequoia 15.7 (24G222)

Additional system information

Machine: Macbook Air 2025
CPU: M4
RAM:24GB

CAD Used: Fusion 360

Bug: The program crashes when trying to slice more than a few objects.

What I tried:

Reboot
2.Update macOS
Re install Orca
Install Orca 2.3.1 beta
Install Orca 2.3.1 nightly

What fixed it for me:
Changing draft shield from individual to combined.

----------- Extra -----------
I attached my printer config and my profiles.
The only profiles I use draft shields are the ABS Profiles. The bug occurred specifically using the "ABS Strong All Metal" profile.

Printer

Custom SKR Pico Ender 3 Pro

How to reproduce

Load model in Orca
enable per object shields
Clone it about 8 times
Slice

Actual results

The program crashes.

Expected results

The program slices irregardless of draft shield type.
