It is not possible for me to render the attached test scene in the viewport without the blender or the whole pc crashes.
The final rendering by tiling is not a problem
Either the viewport remains dark and you only see the outlines of the objects or there is a shading as with ambient occlusion only in grayscale. If you continue to render the pc crashes completely at some point
Vieportrendering with only the cpu oder final rendering with tiles and gpu is ok.
