Sentinel 1 GRD data

I have imported the GRD Sentinel 1 data - did not save it to disk
I selected it then subset a part of it - I saved the subset using “Save Product as”
After saving the VH amplitude file , at 50% it goes off without showing any error.
The VV amplitude file is NOT getting saved - it shows blank file, however VH is getting properly saved.

I tried with 2 different files - using 32bit SNAP latest version

Can anyone suggest please

did you save it in BEAM-DIMAP format or another format?
