First, some technical elements out of the way:

• OS: Ubuntu 25.04
• CPU: Ryzen 5600x
• GPU: Intel ARC A770
• MESA: 25.0.3 (can’t get 25.0.4 from Kisak because they’re currently not supporting Plucky).
• Blender3D: 4.4.1 (though the same problem occurs on the previous 3 versions of Blender).

I had decent performance in Cycles with my new card, but didn’t have BVH raytracing support and Blender told me to get “level-zero-raytracing”. I found this on GitHub, and checked on forum posts if this was indeed the thing I needed, then built it following the instructions.

The resulting “libze_intel_gpu_raytracing.so” file I placed in my ~/usr/lib directory. Then rebooted my PC for good measure.

Now when trying to render in Cycles it throws the error in the title.

I can probably just delete that file and go back to rendering without BVH on the GPU, but I’d rather solve it and use the GPU for what I bought it. Has anyone had this issues before? How did you solve it (if possible)?
