I'm using DXO Photolab to pre-process certain files before returning them to Lightroom.
After the NR/sharpening in DXO, I click "Export to Lightroom". I can watch the green progress bar moving across the Photolab icon. It usually gets so far and then gives up, the whole thing turning red.
Sometimes the export works successfully and the exported file appears where it should , both in the Collection DXO created for this purpose, and in the folder next to the original.
If it does, and I examine the exported file carefully, I often find that it is corrupted - typically with a rectangular area within the image which has a network of short, coloured, straight lines running across it. (typical example attached)
Sometimes a successfuly export will only appear in the DXO Collection and not back in the original folder.
I have been speaking to DXO about this at great length without any success. Is it a Lightroom problem?
Lightroom v12, Windows 10, DXO Photolab v5.6.

You did not attach an example. Please use the "Insert Photos" icon to include an example.
Corrupted files are almost always the fault of a hard disk malfunction. I really cannot imagine software, either Lightroom Classic or DXO, causing some file corruption.
Nor can I imagine Lightroom Classic causing DXO to show a red bar when exporting.

I provided specific instructions on how to include your screen capture. This doesn't comply, and I can't view your screen capture.

I have added 2 photos using the Photo icon instead. The almost black photo is the result of usingPureRAW in the same way to preprocess a file.

I don't see them anywhere.

These are corrupted photos. The cause of the corruption is almost certain a hardware malfunction. Either hard disk malfunction, or bad memory chips. One thing you can do to see if you can isolate the problem: if you have different drives to do this with, is to store your photos (both before and after using DXO and while using Lightroom Classic) on a different disk.

Thanks .
I do have two separate internal hard drives so that may help to solve it.

Would that account for the intermittent nature of the problem?

The first thing that you should try is to switch off the GPU support from the Lightroom preferences and check if that helps to fix the issue.
Go to Lightroom > Preferences > Performance tab > Uncheck "Use Graphics Processor" > Restart Lightroom.

If Lightroom doesn't start correctly the please see "Solution 2" in the document behind the second link.

Another step is to try to reset the Lightroom preferences.

It's recommended to backup your preferences before you reset the preferences to the default settings:

I have turned GPU acceleration off and the first few exports from Photolab to LR have been successful. However, this has happened before. I can get a few successful exports but then they fail again. It's a bit random. I may have to leave this for a while now - Supper Time! - but I will come back to this later. Thanks for your help.

I am not clear if the reply from dj_paige is absolutely definitive as there have been other suggestions. Could someone slarify this please?
