Unable to subset VV band

I am unable to create a spatial subset of VV band. Subsetting option works fine for VH. But the software closes when I try to create a subset of VV. Please help.

I can’t see why there would be any difference. Are you sure the VV band is ok? Can you open it fine without subsetting?

Yes I am able to open it without subsetting. Problem occurs only when I try to create a subset.

I tried again. The subset was created. But the software closed when I tried to save it.
