Terrain Correction operator hangs while processing S1 image

Hey community members!

I’ve faced a problem when trying to process S1 image. I want to subset a 1024x1024 window from the original image and then perform Range-Doppler Terrain correction.

The problem is that when I try to run Terrain correction operator nothing happens. Here is a screenshot.

It looks like SNAP is trying to write some data, but not a single bit has been written to the hard drive.

I tried to process both original size image as well as truncated without any luck.

Any suggestions?
