Scaling Meshing Issue

I'm having a meshing error that I'm having trouble interpreting.
At a small scale the mesh compiles just fine. I'm able to mesh and run the physics simulation without any issues. But when I make one of the parts longer, the mesh crashes and I get an error: "Failed to create swept mesh for domain ... Unsupported topology of linking face" (photo error is also attached)
I wouldn't have been surprised to see an error about mesh element size, but this error says there is something wrong with the mesh domain itself.
When I go back to the shorter size, the model works just fine. The only variable that is being changes is the length of a part. Nothing about the shape or mesh setting changes between the two. I'm struggling to understand how such a change would cause a topological error.
Some more context: - The model uses a swept mesh since the part is a 2D shape that get extruded. - The part is connected to a different part on its surface, but there are no intersections that would effect the meshing differently when the size changes.
Any advice for how to interpret / correct this error?

Hello Nathaniel,
Well, at the risk of saying something you already know, the error message does suggest that the topology of one of the faces along which the mesh is swept is different in the case of the longer size. An educated guess is that it has to do with where the part is connected to the other part. It would be helpful if you could post pictures of the geometry corresponding to both the shorter and the longer cases, or better yet the mph file with instructions on how to reproduce the error. Also, if you could say which version you're using, because the sweep meshing has evolved (gotten more tolerant) over the years.
Best,
Jeff
