Hi Bruno,

First delete your saved and intermediate folder located in your project folder.
Next you need to check the assets mentioned bellow as they are returning errors in your log.

  • /Game/FirstPersonBP/Maps/FirstPersonExampleMap : Can’t find file for asset. /Game/Objects/Plantas/Achillea_millefolium1-MIL_RAMAS/NewFoliageType_InstancedStaticMesh

  • /Game/KiteDemo/Maps/Showcase.Showcase:PersistentLevel.BoldTrigger_Blueprint.BoldTrigger_Blueprint’. Not spawning Actor of class ‘BoldTrigger_Blueprint_C’ to break.

let me know if that helps,
