How to reproduce

Run Orcaslicer Appimage (or aur orca-slicer-bin, or orca-slicer), Open file, enable jpeg thumbnail generation, try to slice, app crashes with Wrong JPEG library version: library is 62, caller expects 80.

Actual results

Running the OrcaSlicer AppImage or the orca-slicer-bin AUR package, Orcaslicer works fine until the point of generating the gcode output image, where it crashes with the following error:

Expected results

Should slice

Anything else?

I haven't installed any libjpeg manually (only libjpeg-turbo is available in the arch repos and is installed by something).

orca-slicer from AUR fails to compile with some error in the AppConfig.cpp
and the Flatpak errors out when running a python post script for the thumbnail (pip isn't available within the container so can't install Pillow), while also not having access to my octoprint through the Device tab. I've tried every single channel of OrcaSlicer and none of them work for different reasons.
