Short description of error
When rendering with cycles with CPU device selected, any kind of viewport denoising Auto/OptiX, etc. crashes blender.
Exact steps for others to reproduce the error
1.Create a new blender file with default cube.
- Select cycles as renderer, with default device as CPU selected.
- Enable viewport denoising, with any denoising option (Auto/OptiX, etc.) selected.
- Click on display render preview for viewport rendering. Blender starts to render, and crashes within seconds.
- Sample blend file attached.
[Based on the default startup or an attached .blend file (as simple as possible)]
