After exporting this error report populates and states that an internal math error has occurred for 18 of the images. I'm not sure how to fix this. Can someone help me out?

I've just had the same issue. 3 of my 147 exported files couldn't export due to the math error. I narrowed it down to using the transform function, and more specifically vertical. If I reset that back to 0 it'd allow me to export. Not ideal given the skewed lines, but it got me through the issue for now.

Achei que o problema era só comigo.
Tenho tido muita dor de cabeça com esse erro.
Começou a aparecer há uns dias.
Alguém já foi respondido sobre o que fazer nesse caso?

Há previsão da correção deste erro matemático interno do Lightroom?

A Adobe já respondeu alguém aqui?

Mesmo problema aqui.

Não exporta as imagens com exclamação e afirma ser erro matemático interno do ligthroom.

Same problem here. I figured out that it only happens when you copy and paste the style from one photo to another, or also when you apply a preset. When you try to export the original file or edit the photo from scratch it doesnt show the error.

So if you want to save some time until this is fixed, my solution is to copy everything from a photo except the Process Version (you will have to uncheck some adjustments) and that's it. You can't copy and paste everything but it's something.

I hope you guys can fix this soon.

Been having same intermittent issue for last couple of weeks , using Big Sur 11.2.3 and LR Classic 10.2. Only way around it is to reimport the photo's from original memory card and reimport into LR..... pain as internal math error only happens when exporting... so can send ages editing and then find you are xxxxxxx.

Once error occurs the files are marked in Library with a black circle and exclamation mark.

This time it impacted 25 images that I had edited. So 50 successfully edited and exported. All images from same camera (1DX) imported as CR2 and export was jpeg, 2 jpeg sizes used full res and longest edge 1920px.

Have checked the the original CR2 in the LR files location can be edited in photoshop.

Ask if you need anything else

Can you open these images with another application such as the Photos apps included with macOS or windows?

Please supply additional information:

  • operating system and version
  • Lightroom version

Lightroom Classic is unable export 18 images. Lightroom says, "Internal math error occured". This has never happened before. I also reset all the "Adobe Lightroom Classic CC" preferences by uninstalling and reinstalling Adobe Lightroom Classic. Please help me thank you.

On my Windows machine, back on the Lightroom version 8 and 9 releases, this sometimes happened to me. But it hasn't happened on V10. When it happened, the fix was to just redo the export. It would sometimes happen on import as well.

  1. Which Lightroom product are you using, I'm using LRC? 
  2. Which version of Lightroom?
  3. What operating system and version?
