I attached last part of output log.

CookResults:Error: Error Couldn’t save package, filename is too long: C:/Users/Ragib Hasan Supanta/Desktop/Uni Project Final/14201009 4.16/Saved/EditorCooked/WindowsNoEditor/Project3/Content/InfinityBladeGrassLands/Environments/Plains/Env_Plains_Ruins/StaticMesh/SM_Plains_Ruin_BuildingLOD02.uasset
