Fnis Freezing and Tposing issue

[NamaNama]

I have Skyrim Special edition and I generated Fnis behaviors successfully before, but now the programs freezing since I installed jcontainers. It won't finish generating behaviors I have no idea why.

I'm not sure if the mod order helps at all, since it seems the program just refuses to work... or its extremely slow. 

This might help to know that I did download a animation pack from here and used nexus to install it which could be the issue. 

 

EDIT: I think I solved the issue
