The licensee shared information that a Null check on the following Actor can be used as a workaround.

static TArray<UActorComponent*> GatherHLODRelevantComponents(const TArray<AActor*>& InSourceActors)
{
TArray<UActorComponent*> HLODRelevantComponents;
 
for (AActor* Actor : InSourceActors)
{

1. Open the attached project PL_C01_8K.umap.
