Snaphu-unwrapping error

Hello there.
I am facing an error while unwrapping the face with SNAPHU Unwrapping plugin on windows (64 bit).

I’m trying to understand if I’m making any mistakes running the step-by-step tutorial “RUS Demo: Land Subsidence mapping using Sentinel-1”.

Please help me find a solution.

Looks like coherence hasn’t been exported. Can you please check if the coh_ file is im the folder?
If not, please make sure it is created with the interferogram.

I found the cho_files and put them inside the Snaphu folder.

Now i’m having this error:

Sorry, can’t tell what is wrong. But you have higher chances to get it correct if you apply the steps one by one instead of a graph. Carefully check the output of each step before you proceed.
