Crash when destroying a geometry collection actor

When an actor with geometry collection is destroyed,
the engine doesn't remove elements from array in the ChaosSolver
So illegal references occurs.

Removing element with following quick fix code can avoid crash on 4.25. (it doesn't work on 4.26)
However, this is probably not correct.

	bool FPBDRigidsSolver::UnregisterObject(FGeometryCollectionPhysicsProxy* InProxy)
	{
#if 1  // quick fix
		RemoveDirtyProxy(InProxy);
#endif  // quick fix
		InProxy->OnRemoveFromSolver(this);
		InProxy->SetSolver(static_cast<FPBDRigidsSolver*>(nullptr));
		return GeometryCollectionPhysicsProxies.Remove(InProxy) != 0;
	}

void FGeometryCollectionPhysicsProxy::OnRemoveFromSolver(Chaos::FPBDRigidsSolver *RBDSolver)
{
	const FGeometryDynamicCollection& DynamicCollection = PhysicsThreadCollection;

	for (const FClusterHandle* Handle : SolverClusterHandles)
	{
		RBDSolver->RemoveParticleToProxy(Handle);
	}
#if 1  // quick fix
	for (FClusterHandle* Handle : SolverParticleHandles)
	{
		RBDSolver->RemoveParticleToProxy(Handle);
		RBDSolver->GetEvolution()->DisableParticle(Handle);
	}
#endif  // quick fix
}

on 4.25

1. # Open attached project on ue4.25  [Link Removed]
2. start PIE
3. Wait for 5 seconds
4. Editor crashes

on 4.26

1. Open attached project on ue4.25  [Link Removed] (Easier to reproduce with DebugEditor build )
2. start PIE
3. Wait for 5 seconds
4. Approach the location where the geometry collection was located.
5. Editor crashes
