Error Interferometric

hi guys

I’m interested in learning about interferometry, I started to follow this tutorial (https://www.youtube.com/watch?v=Gtopm6VLr_4&list=PLiuUQ9asub3SI5jSVOY4lmddsPSLDUrXq&index=4)
with exactly the same area but when I reach the interferometry phase the image disappears, different from what should have happened.

In case you selected topographic phase removal, did you maybe select SRTM 3Sec? Because it has problems lately. If so, please run the interferogram step again with SRTM 1Sec instead.
