Packaging error

Hi, I have been trying to package my project and it fails all the time.

It stops packaging here:

“PackagingResults: Warning: Failed to load ‘/Game/Materiales/corda3’: Can’t find file for asset
‘/Game/Materiales/corda3’ while loading NULL.
LogSlate: FSceneViewport::OnFocusLost() reason 0
LogSlate: Window ‘Output Log’ being destroyed

LogSlate: FSceneViewport::OnFocusLost() reason 0
LogSlate: Window ‘Output Log’ being destroyed
LogSlate: Window ‘Output Log’ being destroyed
LogSlate: FSceneViewport::OnFocusLost() reason 0”

I would love some help. Thanks!
