Mcreator Mod works but loading in game, it errors. Not my code elements, something else

I loaded mcreator, opened game in current state, it worked. Cloded game, added 3 new elements, simple ones that shouldn't bug at all, i;e new normal blocks. Instant error upon loading the game, not in mcreator. I tested to see if it was anything, and yes any new element added to my workspace crashes it. *

A clear and concise description of what the bug is.

Details

  • MCreator version: [2021.2 (Bug Fixed Patch One)
  • Generator type: Forge-1.16.5
    Windows 10

Steps To Reproduce

Have a mod w/ 105 elements. Load it in game, = fine.
Add 3 new elements of any kind, it will pop up an error code in game saying, "can't find registries"

108 elements in workspace

Added Working & Non Working Workspace

Working Workspace
Not Working Workspace
