What does CSG Returned Error Code -11 mean?

Okay so basically, I was building a CSG model in Roblox Studio until I got slapped in the face with this error

I don’t know if it’s the triangle limit, I don’t think it is considering the fact I’ve looked into wireframe mode and all I see are no triangles

The model does not have that many triangles from what I observed, but when I still negate, I still get the error regardless. I’ve looked into this article

And still can’t seem to resolve the issue, but nonetheless I highly doubt it’s the triangle limit. Any help?

Hey. Can you try unioning different parts of the model and check the problematic ones?

If you can, please send me the model you have an issue with and I will investigate the problem.

I have the same problem with multiple of my CSG builds currently, are you able to look into it again?
