just looked at your logs and its because your level data is larger than 2GB.
FMemoryWriter does not support data larger than 2GB.

Possible Solution: Ensure your lightmaps are compressed and try splitting level into sub levels if possible. To compress your lightmap goto the worldsettings and check Compress Lightmap. If it still doesn’t work go through your assets and reduce the lightmap size.
