Problems to import images from external ssd with exfat

Hi! Did encounter problems to import more than approx 600 images from my new external ssd with exFAT.

Lightroom just hangs during import. I have tried my setup on several other computers with no sucees. If I change the filesystem to NTFS lightroom will be able to import. I am running windows 11 and tested in win 10 as well.

Is it a bug, or am I doing someting wrong?

Cheers Daniel
