When I was running macOS Mojave and the earlier version of Canon Digital Photo Professional (DPP) version 4.11.0 or 4.10 (not sure what the earlier version was) everything was fine, I was able to edit and print photos, everything was great.
When I was still running macOS Mojave and updated to DPP 4.11.1 a couple weeks ago I started having issues opening and trying to print photos shot by a professional photographer with a EOD 5D Mark3. I get a message such as "unsupported image" or "target file not found". I can see some of the photos as thumbnails while others just show a question mark (if I wait a long while they seem to all show up as thumbnails but still have a question mark), if I pull up a thumbnail I can see it appears sort of low resolution/pixelated. If I try to print it I get a message “target file not found”.
I updated to macOS Catalina 10.15.2 and am still running DPP 4.11.1 which I believe is the latest version but I am still having the same issues. To make it stranger, photos that I edited by cropping to square or adjusting the exposure prior to installing DPP 4.11.1 are fine and they are in the same folder with the originals.
I went back and tried the files on the original thumb drive but still have the same issues.
My photos shot on a Canon G7 or 6D all seem to open fine.
Do i just need to wait for an update to DPP 4.11?
Any ideas? Thanks
