cannot find symbol error variable block_BLOCK

Hi! i'm having a problem everytime i try to create a block.

I'm using Mcreator 2020.4 with fabric plugin for mc 1.16.3.
I'm mostly sure it's not the plugin fault cause i tried doing the same with the forge compiler but still the same error.
I already tried clearing the cache but nothing changed.

That's the console error:

Any clues? I only have this problem when creating blocks, items and other stuff works perfectly.

Thanks!
