DxO Photolab not showing preview or opening .DNG images

I suddenly can’t open .DNG image from my Leica M10R.

Not en I copy the folder with files to my local disk or directly from the memory card.

I still had a card with images from a previous shoot that I could process but now can’t read anymore.

I can open the .DNG files with other applications and macOS Finder shows the previews.

Photolab 9 is up-to-date.

What to do?
