check(!bPostTickComponentUpdate) fails triggered by UNiagaraComponent::CreateRenderState_Concurrent() and StaticMeshCompilingManager::FinishCompilation()

Reported alongside [Link Removed]

Context: Some ActorComponents can schedule end-of-frame work which UWorld executes later in the frame in UWorld::SendAllEndOfFrameUpdates(). By-design it appears that it's not allowed to schedule more end-of-frame work while executing such work, since this assertion in MarkActorComponentForNeededEndOfFrameUpdate() is meant to catch that:

check(!bPostTickComponentUpdate); // can't call this while we are doing the updates 

The provided callstack shows EOF work scheduling more EOF work so this should be addressed.

Issue: No specific repro steps provided except that NiagaraMeshRenderer is involved and the crash isn't reliable to repro. Looking at the callstack it seems that 

UNiagaraComponent::CreateRenderState_Concurrent can cause FStaticMeshCompilingManager::FinishCompilation to be called, which causes some component to ultimately call UActorComponent::MarkRenderStateDirty(). This is not allowed while inside SendAllEndOfFrameUpdates() so should be addressed somewhere along the callstack.
