Sometimes Blender just crashes like that. Luckily it is a simple scene and you can try the one by one trick. What I do is open a new blend file, Take the helmet, render in Eevee since that’s what giving you troubles, if it’s all fine then take another element, render again, and so on until everything is on the new blend file or it crashes as soon as you introduce a new element, that way you know which element is the buggy one and you can leave that element behind and remake it from scratch in the new scene.
