I use Lightroom Classic Ver 9.4 ... and I'm seeing my image files disintergrate before my eyes. Is there anyway to stop this and possibly fix the the files that have become corrupted? I'm also then unable to open in any other image application.

First, try disabling GPU in the preferences (Preformance). Any better?
If not, recalibrate and build a new ICC profile, the old one might be corrupted.
If you are using software/hardware for this task, be sure the software is set to build a matrix not LUT profile, Version 2 not Version 4 profile.

Thank you for responding. I'll turn off the GPU and see how it goes. Not sure what an ICC profile is! Will research ... Cheers

From what Ive just read ICC profiles are for printing not for screen display... have I misunderstood something here?

Looks more like a corrupted RAW file. Now, the embedded JPEG may not be corrupt, hence it looks ok when viewing on back of camera, and looks good when first importing the RAW as you first see that embedded JPEG before LrC creates a preview.

"These files have been on my computer for some time."

 

Yes, this is a clear indication of a hard disk malfunction somewhere.

That was my thought as well, but the files were sitting on an external drive which I replaced with a brand new drive. It seems that I'm having the same issue on the new drive as I had with the old one.

What do you mean by "The Same Issue" with the new drive?

Did you Copy over those same files from the old drive to the new?

Copying corrupted files to a new disk does not uncorrupt them. They remain corrupted.

 

You need to restore the photos from a recent backup.
