LRC images sporadically being corrupted

What is happening so some of my photos? They look fine the Library preview mode but if i switch to develop mode, some of them are corrupt. They originally show and then (i am guessing) when the preview is being replaced with the actual image load they start getting corrupted. I even tried to delete them and reimport them from my backup drives (I have 2 backups) but still bad. I cannot decide any rhyme or reason behind them. As in shot by this body, imported at this time, etc. Added an image to show what is happening. Each corrupted image has a different amount of corruption its not the same but it does have the same generic look. So all 3 copies are looking the same. If it were just a couple i would yell but get on. My fear is that this is slowing moving and i might look important ones. Corrupted images are from multiple camera bodies and at one time was able to eidt in LR.

Corrupted files are caused by a hardware malfunction somewhere. In your case, I would suspect either the hard disk or the computer's RAM. Naturally, if you have backups on a different drive, you are protected against losing your work and protected against losting your photos.

i pulled the files into both my laptop catalog and my mac mini catalog.. both are showing the same corruption that was not there in the past when i imported and processed the photos. So that led me to think the files were corrupt so i did a harddrive disk utility first aid. That found no issues. So i connected my 2 backup drives and imported the backup files to both catalogs and still corrupt. I am at a loss. I cannot believe both computers LRC and catalogs are identically bad. I also cannot believe that all 3 versions of the files are suddenly bad. I know thats not much to go off of. none of the files were edited in any other software just LRC. Of course in older versions of LRC. So at this point the photos are lost even on my backups. Any Any Any suggestions before i completely stress out about losing all my other photos over time?

To add to the confusion and the idea that its actually LR. I picked one of the bad photos that were bad on the actual library and was bad on both back up drives and were bad regardless of which computer they were open in a different LR...  I opened the CR file with DXO Pure raw and it rendered correctly. I then saved it and imported the saved DXO pure raw file and it now renders in LR correctly. Come on it has to be something with LRC.

as a side note. After the CR file opened properly in DXO, i deleted the associated XMP file with the file and tried again to see if somehow the XMP was causing the problem, but it was still corrupt in LRC with no XMP file

I think this might be a GPU issue.

In the LrC preferences, go to the Performance tab and set Use graphics processor to Off.

Does that make any difference?

While I don't have an answer as to what is happening, please know that Lightroom Classic never (cannot, it is not something that the software was programmed to do) write to the image portion of your photo files. So, LrC cannot be causing image corruption.

 

Please share one of these photo files on Dropbox or similar platform, and provide us the link, so that we can see how LrC handles these photos on our computers. UPDATE: looks like @Per Berntsen has a better path forward than my suggestion; please try that first.

here is the link to dropbox "adobe" it has 2 files. the CR2 file that has the same corrupted view in LRC from 3 file locations (active photo folder and 2 backup locations). along with importing to 2 different computers with different catalogs. The second file is from importing the "bad" file into DXO pureraw and then saving as a DNG.

The CR2 file displays fine in LrC 13.1 at my end. There seems to be nothing wrong with it.

Did you restart LrC after disabling the GPU?

I did restart but to no use.. I will try disabling the GPU on my other computer and its LRC instance. I usually do not use that computuer as it is older and I cannot up the OS and therefore cannot move to LRC 13.1 on it. The most important thing is it renders correctly in your version of LRC 13.1 which give me great peace of mind while i continue to troubleshoot to know at least the files are good.  Not sure why my LRC instances are having issues I just need to figure out what is wrong with my both my versions and instance. Thanks for all your help. If i ever figure out the ultimate culprit i will add to this post.

The screenshot you posted looked very familiar, there was a period some years ago when it came up almost daily, but I haven't seen it in a long time.

I'm pretty sure that it was fixed by disabling the GPU, or updating the driver.

I'm on Windows myself, but if you have an older Mac, it could be that your graphics card is no longer receiving driver updates.

Have you already tried deleting the camera raw cache? Preferences->performance->Purge Cache. Then quit and reopen Classic. Both the files you linked to work fine on my machine. This could be simple cache corruption.
