Editor crashes when fracturing with Dataflow

Editor crashes when duplicating and using an existing dataflow graph.

This did not occur in the original graph.

The crash does not occur if the fracture occurs due to collision, but occurs if the fracture occurs due to Apply Strain being executed in Blueprint.

The error is this.

Assertion failed: Pair != nullptr [File:D:\build++UE5\Sync\Engine\Source\Runtime\Core\Public\Containers\Map.h.inl] [Line: 648]

Does anyone know how to solve this error?

I recreated the geometry collection and dataflow graph from scratch, but it still crashes.

Specifically for geometry collections crash even when using dataflows that worked.

I have discovered the cause.

It seems to crash if the GC Cluster Connection Type is left as default.

Changing to Chaos Point Implicit no longer causes a crash.

The data flow was innocent.
