Can confirm that this mod causes this error.

"Error while loading recipe prototype "uranium-ore-patch-taffy" (recipe): Key "icon_size" not found in property tree at ROOT.recipe.uranium-ore-patch-taffy

I have same issue

Can you tell me what mods you're using?

Artisanal Reskins: Bob's Mods replaces the icon of the robots with a layered one (the tier gets added). This means there is no longer an "icon" property to copy, because it uses "icons".
As a solution you could instead either hardcode the vanilla icon or fallback to "icons[1]".

I just replaced the old 'table.insert(icons, {...})' with 'table.insert(icons, {icon = "base/graphics/icons/construction-robot.png", icon_size = 64, scale=0.25, shift = {-8, 8}})' and factorio loads again
