I experience a strange behaviour in the Lightroom import funtion:
When I want to import pictures (.jpg) I can select the ones that I want, even the preview is working. Then they are imported and shown as thumbnails - so far so good.
But - a few seconds later the thumbnails get completely black - one by one. When I try to edit such a picture it's also just black. Nevertheless the metadata can be accessed. The pics are coming from different cameras.
Every other software can read them as it should.
I have tried to delete them from catalog and reimport - the error can be reproduced.
I'm on Windows 10. The issue came up with one of the last updates. Before it went correctly.
