Cannot invoke "net.minecraft.resources.ResourceLocation.toString()" because the return value of "net.minecraft.core.Registry.get

[EthTDP]

I was wondering if anyone can help me. Whenever I try to load into a new Minecraft world, the error in the title pops up.

I am not sure why.

Here is the full crash report:

The error says you have a bee with an attribute. But the attribute has not been registered with minecraft/forge.

Since you only have 2 mods, just remove each of them individually and see if it fixes the problem?
