Bug with PSD - transparency issues - display, convert to PNG

[TobaCreations]

I am having serious trouble with this Photoshop file. It doesn't display properly in both [XnView MP Windows Version 0.96 64bits] and [XnConvert Version 1.80].

I have encountered many problems with converting PSD files with transparent background, but this is problem with whole image. I would love to use XnConvert for converting PSD files, but at the moment, most of my transparent PSDs end up as PNGs with white background - unusable

Source Photoshop file is a relatively simple image with transparent background. Color profile (or in PS „Color mode“ is set to RGB color)

When converted to PNG using XnConvert, image on output is just white - same as the preview inside the program (sometimes the image displays properly on the „Input“ tab, but with low resolution)
When opened with XnView, the preview (of PSD file) is also displayed as just white image.
