Creating image problem

Hey all,
I am using SNAP S1TBX version 7.0.2 and my laptop has 32 GB ram and i7 3.2 GHz. I updated my SNAP from 6.0 and now I couldn’t create image. I am using Graphbuilder TOPSAR Coreg IW All Swaths and I want to see Phase and other bands but I can see only "creating image for ‘Phase…’ " as I attached. I increased the RAM in the cache section as 12000 mb and nothing changed. I also tried to open other bands from initial SAR data and it works good but not open processed data results. Please help. Otherwise, I need to reinstall the previous version of SNAP.
