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?

"an internal mathematical error has occurred"

An Acknowledged bug. See-

I had the same problem, a preset for some reason causes this problem, I had 170 photos of which 7 had a problem with this preset. change to another preset and issue fixed.

I have found that when I run into this issue its bc I synced a good bit of images at one ti.e. if I delete and import the images that are marked as error, then I can then edit and export. Sometimes I sync more than 50, or even 100 images at one time. If I have multiple edits on the image, such as radial filters,etc, then that is when I encounter the problem. I currently run iMac, latest update. LRClassic.

Why is this still happening, being a known issue since April? No fix yet? I'm about to lose my mind dealing with this multiple times just today. It's absolutely destroyed my workflow and productivity after 8+ years of Lightroom reliance. 😡

This problem has NOT been answered. I have been dealing with this Internal Math Error during export for months now. It is adding many hours to my work flow and is seriously making me consider making the swtich to CaptureOne.

Literally can’t get anything done. Just edited 500 photos and can’t export any of them due to “internal math error”. All photos are present. I’m so pissed, come on Adobe.

This really sucks! I am having the same issue. I have uninstalled, changed various settings and still no resolve. This is extremely frustrating and is impacting my business since I cannot provide the images to my clients. I am now apprehensive about processing my future work cause I'm afraid I will encounter the same issue. Is there any progress? This is unfair considering I am paying for this and I am unable to use the most important component.

Hello! I'm facing the same issue. I don't know if this has to do with installing the software again in a new computer, it didn't happen before. Please, Adobe, fix this issue, we are paying for using this software and it's not reliable.

Bom dia,

Estou enfrentando o mesmo problema, ao concluir as edições no Lr coloco para exportar e todos os últimos catálogos deram problemas em várias imagens. Meu fluxo de trabalho está sendo super comprometido devido a esses problemas, e estou tendo a meses já vários atrasos nas entregas por causa desse problema de exportação. Pagamos uma mensalidade e ter esse problema tem nos complicado.

"wonder why this feedback post has not been migrated to the community"

I reported it to Rikk Flohr -- they're still working through some missing-content issues, I think.

I just have the same issue.
Your suggested solution doesn't work!

Where is a solution for this?

I need to deleiver to a client tomorrow ans 1/3rd of the images won't export!
It seems random One iomage does, the next doesn'T export with pasted settings of the image before.
If I reset the seetings it exports. This must be some preset issue WTF Adobe!

Google translation: "Export calculation error. Hello, everyone. I have the following problem with the export, 1007 images successful 43 I cannot export at all. Does anyone have any idea what it could be? I am grateful for any help.

"Some exports were not performed. An internal calculation error has occurred"

Adobe has acknowledged this bug, which in general occurs quite infrequently but happens repeatedly for a small number of people:

Unfortunately, no workaround has been posted. You could try rolling back to a previous version of LR:

After applying the color preset to raw files, Lightroom indicates internal math error when exporting photos. If the color is not applied they can be exported well. This error does not always happen, it happens in a random way in some photos. Big Sur OS 11.6 and Lightroom Classic version 10.4. I thought that updating the operating system and Lr would solve it. I work from an external hard drive. I have copied the photos to the computer and I have created a new catalog to prevent it from going through the hard disk and the usb, and it does not work correctly either. Could you please give me a solution for this problem, or if someone has found himself in this same case, indicate how to fix this error? Thanks

Usando o Lightroom Classic ao exportar minhas fotos, acusa o erro de ERRO MATEMATICO.

Ja estou com esse problema a mais de uma semana, e não encontrei solução ainda.

I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the LRC forum so that proper help can be offered.

What is that error again? Do you have a screenshot? And could you copy/paste, any text in that error message, or carefully type it in a reply as we can use Google Translate?
