GeometryException: internal error from within GeometryEngine.Difference(...)

I've been using the project https://github.com/EchoParkLabs/geometry-api-cs which seems to be derived from here. I ran into the error _GeometryException: internal error_ in a specific case.

The error occurs from running the following:

`com.epl.geometry.GeometryEngine.Difference(p1, p2, null)`

where `p1` and `p2`are specified below. The exception is thrown here within `TopologicalOperations.RestorePolylineParts_()`:

int fromEdgeTwinNext = m_topo_graph.GetHalfEdgeNext(fromEdgeTwin);
if (m_topo_graph.GetHalfEdgeTwin(toEdge) != fromEdgeTwinNext)
{
// Crossroads is here. Pass through the crossroad.
toEdge = TryMoveThroughCrossroadBackwards_(fromEdge);
if (toEdge == -1)
{
throw com.epl.geometry.GeometryException.GeometryInternalError(); // ⁂⁂⁂⁂⁂
}
}

with the full stack trace below.

Using `OperatorDifference.Local()...` does the same thing.

I'd be happy to provide any other information that might be helpful. I've tried step-tracing the code but really don't have enough context to understand where it's going wrong.

I'm looking for a workaround, if possible, and also just wanted to report the potential problem in this repository. (Despite this code coming from the other repo as noted above, it could be that the same issue exists here).

Thank you!

`p1` is:
