Updating shader with normal map (4K) in rendered or look-dev mode causes Blender to crash. This was while using a normal map node.

Open new file. Create plane. Apply material. Change viewport to look-dev or rendered mode. In shader editor, import normal texture (4k in this case), apply map and texture coord nodes. Connect normal map to normal node. Connect normal node to normal slot on shader. Crash.
