S-1 Enhanced Spectral Diversity error: "A problem occured during the target product processing"

I am trying to replicate the RUS Webinar “Land Subsidence mapping with Sentinel-1” on a pair of S-1 images, both images are IW-SLC, same track (but different orbit) and both descending. I am running SNAP 7.0 on Ubuntu 18.04 and I have 35GB free space. I have succesfully applied ‘Apply Orbit file’ and then ‘S-1 Back Geocoding’ but when I try to apply ‘S-1 Enhanced Spectral Diversity’ I get the following error, which is not solved even if I tried to tweak the parameters:

A problem occured during the target product processing
Type: OperatorException

how many bursts have you selected during TOPS Split?

Just 1, my whole study area is within a single burst.

ESD corrects shifts between multiple bursts. If you only have one, you cannot apply it.

A problem occurred during the target product processing. Type: OperatorException Message: Executor already shutdown!!
Anyone knows something about this error, while ESD operator,
Thanks,

I had same problem too. Did you find some decision? In my case I have two bursts but it is still not work.

Hi,
I uninstalled last updates from SNAP, or reinstall Snap without applying updades,
Cheers,

I am also facing the same issue with ESD in SNAP 7.0.

I still haven’t found a solution. If you will find this, please let me know. Thanks in advance!

@jun_lu Was the ESD operator changed recently? I don’t have an explanation for the “Executor already shutdown” error.

ESD operator has not been changed since Feb, 2020. I’ll look into the issue to see what caused the problem

I have selected 3 bursts during S1TOPS split and successfully applied orbit files then back geocoding. I can’t proceed beyond the enhanced spectral diversity step. Should I reinstall snap?
