Snaphu - unwrapping

Hi, I’m a student who just approached SNAP. I’m following a tutorial but having some problem with the use of SNAP on windows. In particular with the phase unwrapping plugin:
There is no ouput product. I upload some screenshot for clarity. Thanks for your help in advance.

have you seen the notes on troubleshooting snaphu in this tutorial? Displacement Mapping with Sentinel-1 (especially page 17).

How much time this usually takes? I am using an I7 processor in Windows OS with 16GB of RAM.

the time increases exponentially with larger rasters. I recommend using snaphu from the command line.
