Debian: Illegal Instruction when adding filter

[iam-TJ]

Debian 12 Bookworm amd64.

Solution to the first problem of the plugin not being found (Issue #95) is to sym-link it into the correct location for Debian/Ubuntu and derivative distros expected location as dictated by the obs-studio package itself.

$ sudo ln -s /usr/lib/obs-plugins/obs-virtualbg.so /usr/lib/x86_64-linux-gnu/obs-plugins/

(the Debian .deb package should install to this location).

OBS now sees the plugin and can add it to a source as a Filter but as soon as we try to add the Effect by pressing on the Effects + button OBS crashes with:

...
info:   Loaded Modules:
...
info:     obs-virtualbg.so  
...
info: [Virtual BG detector] detecter_create version:v1.2.0
info: User added filter 'Virtual Background Detector' (virtualbg) to source 'HD PTZ Cam (Inside-Out)'
info: [Virtual BG detector] frame size or format change detected
info: [Virtual BG detector] video_scaler_create success. 1920x1080 -> 256x144
Illegal instruction (core dumped)

Debugging reveals that the illegal instruction actually happens as soon as the filter was selected:
