Crash when rendering sequence

Can you explain in more detail when this crash happens? It appears to be on this line:

CesiumGS/cesium-unreal/blob/v1.31.0/Source/CesiumRuntime/Private/Cesium3DTileset.cpp#L580


      
          this->LoadTileset();
          
          // Search for level sequence.
          for (auto sequenceActorIt = TActorIterator<ALevelSequenceActor>(GetWorld());
               sequenceActorIt;
               ++sequenceActorIt) {
            ALevelSequenceActor* sequenceActor = *sequenceActorIt;
          
            FScriptDelegate playMovieSequencerDelegate;
            playMovieSequencerDelegate.BindUFunction(this, FName("PlayMovieSequencer"));
            sequenceActor->GetSequencePlayer()->OnPlay.Add(playMovieSequencerDelegate);
          
            FScriptDelegate stopMovieSequencerDelegate;
            stopMovieSequencerDelegate.BindUFunction(this, FName("StopMovieSequencer"));
            sequenceActor->GetSequencePlayer()->OnStop.Add(stopMovieSequencerDelegate);
          
            FScriptDelegate pauseMovieSequencerDelegate;
            pauseMovieSequencerDelegate.BindUFunction(
                this,
                FName("PauseMovieSequencer"));
            sequenceActor->GetSequencePlayer()->OnPause.Add(

Which implies that either sequenceActor or sequenceActor->GetSequencePlayer() is a null pointer. But it’s not obvious to me why that would happen.
