Lightroom randomy stops exporting

[Melanie5C45]

Lighroom Classic randomly stops exporting. I'll be exporting single images one moment, and then it simply wohn't export the next. The export bar appears but makes no progress.

I'm exporting to a folder on my desktop, so nothing fancy. I've even tried exporting directly to my desktop to no avail. I can find the RAW file when I go to "Show in finder", so I know it's there. I can open it, so it's not corrupt.

I've updated Lightroom and also reset the settings. I've also reset my computer. I've also made sure there's enough room on my computer to export this photo.

What else can I try?

Hi, thanks for reaching out, and we're sorry about the trouble! You mentioned that you're trying to export the files to your computer's local storage, are the original files also saved locally? 

Please go to the Help menu in Lightroom Classic, then System Info, and copy the text. You can share the text with us by either pasting it as a reply here or pasting it in a text file and sharing the file with us. 

Thanks,
Nikunj

Yes, they're saved locally and I'm exporting locally. And ignore my point re. JPG images being exported fine. Some of them won't export. Here is the information:

I should also mention that I can export these images by going to "Open in Photoshop" and exporting them there. They export in full resolution, so the files seem good.

Also, yes, JPGs are exporting. Just not my RAW files. Lightroom doesn't seem able to handle them, but Photoshop can.

[Melanie5C45]

I have discovered that, by some bad luck, my raw images from my one camera have the same name as the JPG images from my other camera. I was using both cameras at one event. Could this be why the RAW images aren't exporting? How do I fix this?

[Melanie5C45]

Update: Renaming files via F2 didn't work. The RAW still won't export.

As a diagnostic, try setting Preferences > Performance > Use Graphics Processor to Off. Does the problem go away?

[nikunj.m]

Please try the step suggested by John to check if that makes a difference! If it doesn't, please share a sample file with us along with a screenshot of the Export window showing the settings you're trying to export the images with. 

Thanks,
Nikunj

This seems to have fixed my issue. Could you please explain why does this happen, and will the user always have to turn the performance function off before exporting? 
Thank you!

@yarik.petrash: "This seems to have fixed my issue."

If your issue is that exports don't always complete, and setting Preferences > Performance > Use Graphics Processor to Off avoids the problem, then your graphics driver likely needs updating.

Try updating your graphics driver by going directly to the manufacturer's web site, rather than relying on Windows Update or a manufacturer's update utility:

If that doesn't help, please copy/paste here the entire contents of the LR menu command Help > System Info -- that will let us see exactly which versions of hardware and software LR thinks you're running.

Update: Apparently it's only my RAW files it refuses to export. Not the images I accidentally shot in JPG on a rental camera.
