Missing or damaged files?
Hello, all.
I just bought a brand new Canon R6 Mk II.
I've been on several shoots and I'm bothered my some anomaly on two of them.
when I import photos into Lightroom classic the import goes well, all thumbnail previews look good. However, when I go to the develope tab, about one third of them show this:

the file appears to be unsupported or damaged.
the image can't be edited like this. There is nothing different about these files. They were all imported together from the same SD card.
this is the second time this has happened. The loss of these images is devastating. What is going on?
