Is there an existing issue for this problem?

I have searched the existing issues

OrcaSlicer Version

2.3.2rc2

Operating System (OS)

Linux

OS Version

Omarchy 3.3.4

Additional system information

CPU: 12500H (with iGPU)
RAM: 32GB
GPU: NVidia 4060 Mobile

Printer

K1 Max w/ CFS

How to reproduce

Launch OrcaSlicer via Flatpak on Hyprland
Click File → Open (or any action that opens a file dialog)
App opens the file manager, but is unresponsive and crashes shortly after.

Actual results

File Manager (nautilus for omarchy) opens, and then both Orca slicer and the file manager crash.
Before they crash, the file manager window is unresposive. (you can't interact with it)

Expected results

I should be able to open a project or save a project

Checklist of files to include

Log file
Project file

Anything else?

Notes

Portal config is set with org.freedesktop.impl.portal.FileChooser=gtk as recommended for Hyprland
Restarting all portal services does not fix the issue
calc_exclude_triangles: Unable to create exclude triangles appears consistently before crash
The hard crash with no log entry suggests a segfault in the file dialog initialization path
Workaround: none found

System Info

Flatpak runtime: org.freedesktop.Platform
xdg-desktop-portal services: all three running (base, hyprland, gtk)
