Raw photo appears to have been altered after running AI Denoise in Lightroom desktop 12.3
After updating to 12.3 with the new AI Denoise feature, I've seen some cases where the original file will contain an '!' which, when clicked, pop up the message 'Lightroom has encountered problems reading this photo. You will not be able to make adjustments to the photo. I tried making further adjustments to both the raw file and the resulting DNG file and was able to without incident, so far. To make things even more confusing when I was investigating this one of those that displayed the warning no longer displays the warning; I even tried Denoising that photo again, but the warning did not occur. I wish I could reproduce this, but so far I cannot. I've noticed this behavior on 2 different photos from 2 different photo sets, neither shows the warning now.
Anyone else see this? Any ideas?
Here is a screenshot from today when I saw the warning; the warning flag is now gone from this photo
