P: Export Fails with error dialog when Lens Blur is used

I discovered this today after a painstaking couple of hours. I am on the latest LRC 14.2. I am not going to bore you guys on how I found this issue but here it is.

Canon R6 MK2. Shooting RAW.

I was working on some wedding photos and was applying adaptive blur Circle to the RAW files. All the RAW files that had this adaptive blur were failing. Good thing I didn't apply this to all images so I was able to go over my steps and figure this out.

I didn't check all the adaptive blur types but this was annoying time lost as I had also done AI enhance on my images which took forever. It doesn't matter if you enhance or not, the issue persists just for the adaptive blur Circle.

Thank you for being so patient.

Wenn ich den den Haken bei Objektivunschärfe drin lasse, dann kann ich das Foto nicht exportieren. Es gibt eine Fehlermeldung "Exportvorgang wurde nicht durchgeführt".

Hi @Sabine29465214qtrh,

Thanks for bringing this up. I understand how frustrating it can be when exports don’t work as expected.

To help troubleshoot this properly, could you please share the following details:
1. System Information: (Lightroom Classic → Help → System Info… → Copy and paste that here)
2. Please share the original file.
3. Where are you trying to save the exported image? Internal drive, external drive, or cloud-synced folder?
4. Does this happen with all files or just this one? Try applying Lens Blur to a different image and check if the export also fails.

I’ve tested this on my end with a CR3 file and was not able to reproduce the issue, so these details will help us better understand if this is file-specific, system-related, or a bug.

Thanks, and looking forward to your response so we can get this resolved!

Best,

Anshul Saini

Adobe acknowledged this bug several months ago:

https://community.adobe.com/t5/lightroom-classic-bugs/p-export-fails-with-error-dialog-when-lens-blur-is-used/idi-p/15155658

A workaround is to set Preferences > Performance > Use Graphics Processor to Custom and uncheck Use GPU For Export.

Until Adobe has fixed the issue, I've found a temporary workaround by disabling GPU acceleration:

- Go the Lightroom settings

- Go to the "Performance" Tab

- Under "Use Graphics Processor", select "Custom"

- Turn off all checkboxes for GPU acceleration (or at least the one for "Use GPU for export")

- Close the settings

- Try exporting again

This solved the issue for me.

After exporting, don't forget to switch back the "Use Graphics Processor" to "Auto" 😉

I have the exact same problem when I export DNG files to JPEG with Lens Blur applied.
My versions:
Lightroom Classic 14.3.1
macOS 15.4.1

Hi @selondon , thank you kindly for your input. Interestingly enough, I tried to export the files with lens blur from Lightroom mobile and it worked. I suppose it's an issue with the macOS version, at least on my end. Both my computer & Lightroom have the latest software updates installed.

So, I found something interesting with this. If I start my edits with "lens blur" and then go on to do everything else....the image will export without any issues. Now, granted, this is only with a couple images I've had issues with...so, it could be a coincidence

Yes, that is the exact error I am getting.

I was able to replicate the failure with the DNG provided by @dustinb31538732 and have opened a ticket to investigate.

When there is an update, this thread will be notified.

Hello Lightroom Community,

I have used lens blur several times before. Since a few days ago, I am unable to export pics with lens blur - Lightroom gives me an "unknown error". I included a photo for reference. I removed lens blur and was able to export pics with no isuue.

When the photo is loading during the export process, the progress bar moves much faster than during a standard export. I just updated to Lightroom 8.3...

I guess firstly check that your Lightroom is up-to-date.
Also, to try and identity the cause of the error, what happens when you try to export from Lightroom Mobile (if 1. You use Lr Mobile and 2. The Lens Blur edits have synced to there).
