EOS R5 Mark II - Adobe Lightroom errors

[mdougc]

In processing my photos in Adobe Lightroom Classic, some photos are rejected with the error message, "The file appears to be unsupported or damaged".

The Canon DPP app also rejects the photos, but the message only pops up for 2 seconds, so I can't exactly quote it.

What's happening?

You are right! I wish Canon would fix the bugs in that web site.

Anyway, the newer version did not help.

You are right! The "Check for update" in the app did not find an update. I wish Canon would fix the bugs in that web site. This is one of several.

Yes, I always launch Adobe apps through Creative Cloud, so I can check for updates.

You are labeled "Moderator", so I am guessing that means you are somehow officially connected to Canon. Therefore I am posting my update to you.

I downloaded the photos again, but instead of using the EOS Utility, I plugged the memory card directly to the computer. The corrupted photos loaded to Lightroom with no corruption error messages.

This leaves me with several possibilities for faults:
1. the cable is bad - but I have had no problems at all with other cameras.
2. the camera firmware - the read/write/xmit may be bad.
3. the EOS Utility - handler bug

Can you suggest a next step? Note that there is another post on this site with someone else reporting a similar experience.
