Packaging complete in seconds but...

Hi! I am trying to package a test project with a default template. After selecting the platform (Windows 64-bit) I receive the message Packaging complete! but the process don’t create any file. There is no error message in the log, the unique message is the following:

LogUObjectHash: Compacting FUObjectHashTables data took 1.97ms

Couldn’t find help in the documentantion and in the forum. Someone to give a light? Thanks!
