The error clearly points me to my block registry of the star_block (nether star block), yet the nether star block code has not changed at all since the last time that I had it working. Also, if I comment out the Item EMERALD_AXE in ModItems, everything works again with no issues. I cannot see anything wrong with the Emerald Axe item, and honestly have no clue what could be going on here. Can anyone help?

Use another super constructor call in your ToolAxe constructor. The one that takes a ToolMaterial, float, float.

Thank you! I'm still confused why the error would point toward my block registry, but that was indeed the actual issue!

Because of static initializers. In order for your BlockBase class to add its ItemBlock to ModItems.ITEMS, all your other static fields have to be initialized. But it can't, and there's no line number because of how static initializers are constructed. 

Just trying to run the client or generate run configurations gives me the same problem. But I have not items even inside the mod

create your own thread, this thread is ancient

and post debug log
