Is there an existing issue for this problem?

I have searched the existing issues
Note: there seems to be existing issues, but in #12315 SoftFever requested individual issues for better tracking. Please feel free to delete this is it only congests things.

OrcaSlicer Version

2.3.2 beta2

Operating System (OS)

Linux

OS Version

Ubuntu 24.04.4

Additional system information

System Info

Machine: Minisforum UM790
CPU: AMD Ryzen 9 7940HS
Memory: 16GB DDR5 4800MHz
Discrete GPU: None
OS: Ubuntu 24.04.4 LTS

Printer

Bambu P1S

How to reproduce

Install 2.3.2 beta or beta2 (both have same issue, currently using beta2) via flatpak.
Load project or stl file (I've attached a simple test file MicroServoTestFit.3mf).
Hit "Slice Plate".
Hit "Print Plate".
Hit "Send"

Actual results

Sometimes gives an error message "std::bad_alloc" then crashes, sometimes just crashes with no error message.

Expected results

Should send the sliced file to the printer and start the print, as previous versions did and the 2.3.2 beta2 appimage seems to do.

Project file & Debug log uploads

Project file: MicroServoTestFit.zip
Log file: $HOME/.config/OrcaSlicer/log is empty, no log file seems to be generated. I tried launching with orca --debug instead of through flatpak, but nothing ever launches. Please let me know if there is a way to force it to create a debug log.
