After encountering this myself, I've worked out that this happens because it's not checking for null before trying to read the NBT from the color upgrade.
This can happen if you cheat in the item with REI and insert it directly without it entering the user's inventory, but it can also happen in survival if you autocraft the color upgrade and insert it with something like a deployer from Create.
This one is pretty nasty because it renders the world unusable. Each time you try to load back it, it immediately tries to render the furnace and crashes the game again. And with the right mods, it's technically possible to trigger this in survival. To recover the world if you didn't have a recent backup, one would have to either use an external editor to remove/edit the offending furnace, or load the world without Better furnaces, which would delete all items and blocks from the mod.
Here's the relevant portion of the stack trace from my own Fabric 1.20.1 modpack:
java.lang.NullPointerException: Cannot invoke "net.minecraft.class_2487.method_10550(String)" because "nbt" is null
