Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

Adobe has acknowledged this bug, which was likely introduced in LR 10.2. The only known possible workaround is to roll back to version 10.1.1:

Hello! Was this issue solved? I can't find any useful solution and I'm having a big problem with clients now. Please, help.

Report · Oct 19, 2021

consegui burlar o sistema contra o sistema. o famoso jeitinho brasileiro.
1. pegue uma foto que não esteja com o erro e edite na ferramenta de crop, gire 1 grau
2. copie as configuracoes de edição
3. selecione as imagens com erro matematico e cole em todas essa configuração.
aqui voltou. se precisarem de mais ajuda me chamem

Hello everyone!
I'm writing for a technical help request related to a problem I'm having with Lightroom that is completely freaking me out!
Since the last update, when exporting, I often run into "an internal math error".
I have noticed that this problem happen often when I "copy and paste" adjustments from one previous photo to another. I tried to select some and deselect others adjustments to see if this could solve the issue but nothing happened.
My way of working and my presets have always been the same since years. This issue is messing me up and slowing down my work a lot, especially when it comes to managing thousands of photos at the same time!
I’ve already tried to downgrade to the previous version of Lightroom Classic, but this didn’t fix anything, it just messed up my catalogs and all my presets...

I read that this could be a common problem, but I didn't find any info to fix it.
Is there anyone else who had the same problem and maybe managed to solve it?

I'm running the latest version of Lightoroom Classic 10.4 Camera Raw 13.4

MacOS Big Sur 11.3.1

MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports)

2,3 GHz Intel Core i5 dual-core

16 GB 2133 MHz LPDDR3

Intel Iris Plus Graphics 640 1536 MB

Thank you!

It's a known bug that Adobe has marked "Investigating". You could try rolling back to version 10.1, though there's mixed reports about whether that works. Read through the bug report for other possible ways people have tried to workaround the bug:
