Nedd help to fix Error while loading an local Prefab

[Bugfinder]

I created a nice own prefab. And after this i try to change the materials from cobblestone to steel with changing the .blocks.nim file.
I made an backup, but now i cant open my prefab... not with the new and not with the old .block.nim.

everytime i get an error:

 

i invested many many hours in this prefab. so maybe someone can help me to fix this useless error

 

 

And here ist the .block.nim file. Maybe it helps...
