Problems when exporting image to kmz format

I have used a GRD image to generate a binary map for water surface. Calibrat-> speckle filtering-> terrain correction. So the final product is in WGS84 datum Lon/Lat coordinate.

However, when i try to export it in kmz format. i met a problem, where the dialog says the image could not be exported. i guess it might be a java - related problem, because i saw a java’s icon in the left up corner.

Any body can help on that? Many thanks!

if the scene is too large, the process stops with a failure. Did you try exporting if a smaller subset technically works?

Probably the same issue as reported here:

thank you! it works when i subset it into smaller pieces.
