Editor crashes (most of the times) when warehouse_0000 level is opened

Editor crashes with error messages similar to the attachment below.

Also, the asset at which this error is thrown is not always the same, i.e., in the attached image the asset name is /Game/Scenes/warehouse_0000/Maps/Levels/Lights_04_area_BuiltData. In the next run, the asset could be something different.

A temporary fix to this issue is to comment out these two lines in DefaultEngine.ini

r.OneFrameThreadLag=0
r.GTSyncType=1

An alternative fix that seems to work is to wait for sometime after opening the Unreal Editor, and before double clicking on the warehouse_0000 umap file.

This approach seems to allow UE to complete its initial loading process, before taking up a new map loading task.
