SNAPHU ImportOp Error

I’m facing this error during SNAPHU Import. I have checked whether the folder contains the hdr files as well. So I don’t know the source of this error.
Any kind of help would be appreciated.

Which products exactly did you select in tab 2 and 3?

These are the 2 inputs

I have also unticked this option

I think in tab 2 you shoud selec the inteferogram prodct which is already opened in snap (not the img file), simply from the drop-down menu (not the […] button).
In turn, in tab 3, you select the hdr of the raster created by snaphu.

Some graphical guidance is given here: Problem in Snaphu Import section
