If you give yourself any item with the following NBT, it will cause the game to crash!

{AttributeModifiers::"generic.armor",Name:"generic.armor",Amount:0,Operation:0,UUIDLeast:647294,UUIDMost:425919}" target="_blank" rel="noopener">{{color:#ffab00}AttributeName:"generic.armor",Name:"generic.armor",Amount:0,Operation:0,UUIDLeast:647294,UUIDMost:425919}}

This will only happen if the player holds the item in his hand or if "looks" at it in the inventory (with the cursor).
