Is there an existing issue for this problem?

I have searched the existing issues

OrcaSlicer Version

2.3.2-beta1, Flatpak release

Operating System (OS)

Linux

OS Version

Debian 13

Additional system information

ROG Ally X
Ryzen Z1 Extreme (basically same as Ryzen 7 7840U) with integrated Radeon 780M graphics
24GB RAM, of which 8GB is dedicated to iGPU
OrcaSlicer beta installed via FlatPak

Printer

Flashforge AD5X 0.4mm nozzle

How to reproduce

Place a primitve, then add another primitive as a part. Set the part to a different filament. Slice the print. When slicing completes, Orca crashes and instantly closes. Single-color prints slice without issue.

Actual results

Orca crashes and closes.

Expected results

...it should work?
