Well it just says that the image cannot be opened. Also if I try to open the file in Photoshop it says that the JPEG string is imcomplete (or something) or that the JPG is corrupted. I've resized long edge to be 1024px.
I've tried to look at the image and it really is 0kb and LR does not write any data into it which is strange for me. This hasn't happened with Lightroom in all the years I've used it. But now it's doing this and it's highly annoying.
