Bug Missing layers + overflow converting ratio denominators

[Alex23329378ibum]

Hello,

I have an annoying bug in after-effects.

after effects suddenly gives me the bug in the middle of a project (overflow converting ratio denominators 17::19)).
The weird thing is that I can still see everything in the preview window and can export successfully, but 90% of my layers are invisible. Anyone seen this?
I searched already for some answers, but changing the framerate of the main footage doesn't help.

This is for a big project, (see 20 video's of 1hour) where I work with a premade "asset's/ template file". I'm thinking the problem lays somewhere in the "protected region markers" wich I recently add too my assets file. I'm going to change this now but would still like to hear your thoughts.

to clarify,

the layers disappear in my timeline, in preview I can still see everything.

I work with 1 source video, the rest (+-50 layers) are motion graphics.

Really impossible to know with such unspecific and generic info or more to the point lack thereof. You haven't even provided system info. These math errors are generic and can occur anywhere from effects to expressions, so we really need to know a lot more. Failing hardware acceleration could be a point and of course using protected regions may cause some weirdness, too, but this is literally a thing where you could spend days and never find anything. As a start I'd also try to import the project in an empty project. That may at least trigger a more meaningful warning that mentions a comp or layer that may be causing this.

Sorry for the incomplete info, but I'm fairly new to this.

I work in team with 1 colleague, he had the same bug after me. So it doesn't seem hardware related to me.

I work with  i9-10885H CPU @ 2.40GHz 2.40 GHz // 64gbram // nvideo quadrp rtx 6gb

The assets file is full of expressions, so I'm afraid it will be trial & error to adjust it 1 by 1 and see where the problem lies.

Approximately, how many layers are there in the project?

If it's happening on a different machine too, probably it's project-specific. If possible, could you share the project file (media files are not needed)? If you'd like, you can DM me the download link.

Let us know.

Thanks,

Nishu

Thank you, I will PM you the file.

it regards a project with 50+layers. The strange thing is also that I can see all my layers in the flowchart & in the preview window, but not on my timeline.

I had also some comps where the main comp had a protected region and some subcomps in that maincomp had also some protected regions, maybe after effects was struggeling with that.
