Short description of error
Crash when changing the Color Surface to White Noise Texture

Exact steps for others to reproduce the error

start Blender wirth default factory settings
with the cube object selected, go to the Material Tab in the Properties editor
in the Surface Panel, change the Base Color of the Principeld BSDF to be a Texture Node (image for example)
change then this Texture Node to be the White Noise Texture
crash

the same occurs in the World Color Surface

note that using the Node Editor (in the Shading Workspace for example) does not crash

I can confirm these crash on Blender 2.83.5, Blender 2.90beta ( e157573fab ) and Blender 2.91alpha ( c65c66320f ). Blender 2.82 is working but in this version wasn't present White Noise texture.
System: Linux OpenSUSE Tumbleweed/KDE, AMD FX8350, 32GB DDR3, GTX690 2+2 GB VRam- Nvidia drivers 450.57, Factory Setting applied.
