P: Can't import astrophotography photos with my S23 Ultra to Lightroom(mobile)

I have been using Expert Raw on my new S23 Ultra and transfered several raw pictures to Lightroom(mobile) and edited them there.

But for some reason it wont accept astrophotography photos.

They are also in raw file and not even that big of a file.

A few was taken with the main 1x camera and a few in 3x camera.

But when i try to import them to lightroom i get the message "Failed to import 1 photo"

I asked in other forums for Samsung phones but doesn't seem other people have the same problem.

Any ideas?
