Is there an existing issue for this problem?

I have searched the existing issues

OrcaSlicer Version

2.3.2-dev build ba5f0e7

Operating System (OS)

macOS

OS Version

see notes below for full crash dump

Additional system information

see notes below for full crash dump

Printer

Prusa Mk4S HF 0.4

How to reproduce

Open Orca. Then try to open a pre-existing .3MF project. Orca opens no problem. But crashes upon attempting to open a pre-existing project.

Actual results

Full crash. See notes below for full crash dump.

Expected results

Orca should open a pre-existing project. It crashed on several different projects (all I tried) so it is likely nothing to do with the project file(s).

Project file & Debug log uploads

*Originally created by @jansabbath on 1/6/2026* ### Is there an existing issue for this problem? - [x] I have searched the existing issues ### OrcaSlicer Version 2.3.2-dev build ba5f0e7 ### Operating System (OS) macOS ### OS Version see notes below for full crash dump ### Additional system information see notes below for full crash dump ### Printer Prusa Mk4S HF 0.4 ### How to reproduce Open Orca. Then try to open a pre-existing .3MF project. Orca opens no problem. But crashes upon attempting to open a pre-existing project. ### Actual results Full crash. See notes below for full crash dump. ### Expected results Orca should open a pre-existing project. It crashed on several different projects (all I tried) so it is likely nothing to do with the project file(s). ### Project file & Debug log uploads this is the top half of the full crash dump: ------------------------------------- Translated Report (Full Report Below) ------------------------------------- Process: OrcaSlicer [1120] Path: /Applications/OrcaSlicer.app/Contents/MacOS/OrcaSlicer Identifier: com.softfever3d.orca-slicer Version: 2.3.2-dev () Code Type: ARM-64 (Native) Parent Process: launchd [1] User ID: 501 Date/Time: 2026-01-06 13:08:41.6459 -0700 OS Version: macOS 15.4 (24E248) Report Version: 12 Anonymous UUID: 6A1846E6-950E-E2AE-9C9E-056D06FE52C6 Time Awake Since Boot: 6900 seconds System Integrity Protection: enabled Crashed Thread: 0 orcaslicer_main Dispatch queue: com.apple.main-thread Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x0000000000000000 Exception Codes: 0x0000000000000001, 0x0000000000000000 Termination Reason: Namespace SIGNAL, Code 11 Segmentation fault: 11 Terminating Process: exc handler [1120] VM Region Info: 0 is not in any region.
