I converted sigma0_VV in sigma0_VV_db, then deleted sigma0_VV band and later tried to save the sigma0_VV_db band in Tiff format but it was not happening and showing the following error:

May I know the reason for this since I want only db band as output for further analysis so how should I export in this case ?

you can export GEOTIff/BIGTIFF,it’s ok！I have already done this。

you have to convert theVV_db band (right-click > convert band) and save your product (File > Save product) before you can delete the original VV which it was based on.
