After Effects Error - Zero Denominator comparing ratios (17 :: 16) error in Ae version 23.6

I would also like to add that I don't want to switch back to classic 3D, this comp needs c4d

I keep getting this error message while working on my project. Sometimes it pops up and then goes away (temporarily) after I click on "okay" 20 times, only to pop up again when I hit space to view my progress. I am using a MacBook pro 2019.

Ok You fix the issue at Version 24.0 but the problem still exist for us whom cannot upgrade to 24.0 as we have older mac systems. I am using a mac pro late 2013 (cylinder) with latest Monterey 12.7.3 / 128 Gb RAM/ AMD fire Pro D500 4 GB /12 Core XEON E5 and i stil have the issue of "zero denominator comparing ratios (17:16)" every time i am pressing play to see my work...... Is this logical ?  i mean to exclude  even we pay for the use of Adobe suite every month? Are we forced to change all of our equipmen t in order to be able to be upgraded? In any case we are ok to stay at  23,6,2 version of after effects if it is working so can you please fix the bug in this version and not in the newers one?

@bingbonger You will have to change versions, either back to 23.5 or move to 24.0.3 or 24.1 to get the code fix. 

@ronnykhalil Can you share a project with us so we can investigate your setup?

I also am having the issue. Im in 24.1.0. There is no video footage, only PS layers. Also no 3D. I made sure all my precomps were 30 fps. 

Still no fix found for the 2023 version, made sure all the comps have the same settings, changed all the comps to Classic 3D even though there is no 3D in my animations, tried reimporting in other projects, still the same pop-up making AE unusable.

The only fix given is upgrading, but I dont have that option and Im sure many others have to still work with 2023. This is a major issue making projects unworkable with a ressource page of 5 pages of people looking for help and still no effecient fix to it...

For those resolving this issue by manually changing the 3D Renderer in the Comp Settings for each individual comp in your project, you can change these 3D renderer settings globally by using this Comp Setter script: https://aescripts.com/rd-compsetter/ It's free!

You can set the 3D renderer to Classic 3D on all comps with it. Good luck!

We've spent a fair bit of time trying to eliminate these zero denominator issues. Give AE 24.x builds a try.

Ok, so I updated full release AE to 23.6.0 and updated my C4D to 24.0.2 with the Maxon app – I then made sure that only the pre-comps for my 3D type are set to C4D 3d renderer, and my main comp that has those 3d type pre-comps in it is set to classic 3d renderer.  The error is gone!  So I guess either the update to AE and Cinema4D fixed it or setting my main comp to classic 3D, and only having my two pre-comps set to Cinema 4D 3D renderer fixed it.
