How to enable RusticCL with darktable 4.6? (opencl fails to init)

It’s hard to send something when it happens with every file I imported.

It happens with CR3 RAWs, Tiffs, JPGs.
Filmic RGB produces black screen when working with Rusticl.

Also noticed the same with Color Balance RGB - another black image.

Tested all other modules, all ok.
So both Filmic and Color balance RGB make the image screen go black.
This happens on X11 and Wayland both.
