Short description of error
Sometimes it renders a pink background.
Exact steps for others to reproduce the error
Open blender, change to "shading workspace". In the cube's material I add a voronoi texture (I tried with wave or noise and it happens too) and a "color ramp" to the color of the default "principled shader"
I move ONLY the sliders or the interpolation of the "color ramp" and render with f12, default eevee. Sometimes the final render render is gray, sometimes is pink.
Everithig is the dafault scene except the "voronoi texture" and the "color ramp"
