Hasselblad 3FR opens black

The sample image https://www.lemkesoft.org/temp/A0001891.3FR opens just black.

But I see no error message in the console or as result of a function.


The file also contains

The file also contains absolutely black preview.
Adobe DNG Converter converts it to absolutely black DNG file.
zip compresses it into 300k zipfile (1:100 compression ratio)

Are you sure the file is not completely black, but contains some image?
