Am getting these errors and I grabbed 4.27-release today:
29>D:/UnrealEngine/Engine/Source/Programs/HeadlessChaos/Private/HeadlessChaosTestPhysicsScene.cpp(1377): error C2664: ‘void FChaosEngineInterface::CreateActor(const FActorCreationParams &,FPhysicsActorHandle &)’: cannot convert argument 2 from ‘Chaos::TGeometryParticle<float,3> *’ to ‘FPhysicsActorHandle &’
