Lightroom mobile images taken on Android phone showing as black files

I have taken a number of images using the Lightroom mobile camera on my android phone ( Nokia 6 2018) The images are not showing on my lightroom files nor are they showing in camera. By that I mean there is only a black screen. A picture which is totally black

Apart from opening in Lightroom I have tried opening a file directly in Photoshop as well and it seems to want to open as a smart object. But then nothing happens after I press the key

Does anyone have any ideas how to retrieve my images?

When I took them initially I recall there was a small image on my screen until I took the next one.

I would attach a file but apparently it has to be a jpg and the file is a DNG

Thanks for any help
