OrcaSlicer Version

Operating System (OS)

Linux

OS Version

Linux Mint 22.1 x86_64

Additional system information

No response

Printer

n/a

How to reproduce

Download OrcaSlicer_Linux_AppImage_Ubuntu2404_V2.3.1-alpha.AppImage
open orcaslicer
select allow only one orcaslicer instance
try to open a file from terminal with command orcaslicer xxx.stl

Actual results

$ ./OrcaSlicer_Linux_AppImage_Ubuntu2404_V2.3.1-alpha.AppImage 
[2025-08-15 13:22:35.273090] [0x00007096ad9fd4c0] [trace]   Initializing StaticPrintConfigs
dbus[2658181]: arguments to dbus_message_new_method_call() were incorrect, assertion "iface == NULL || _dbus_check_is_valid_interface (iface)" failed in file ../../../dbus/dbus-message.c line 1378.
This is normally a bug in some application using the D-Bus library.

  D-Bus not built with -rdynamic so unable to print a backtrace
Aborted (core dumped)

Expected results

New OrcaSlicer terminal command should attach to an already existing OrcaSlicer instance, like it does well on windows. Linux users should also be able to use the one orcaslicer instance feature either with xdg-open or other ways.
