See this part in your logfile:
System.IO.IOException: The file or directory is corrupted and unreadable
Something is wrong with a file in your project. You could try to migrate your level to a new project and see if you can package from there.
If the issue is with the EngineFont (not sure if its that, but it is the file right before the error), i would recommend going to the launcher and select “Verify” instead of “Launch” for the UE4 version you are using. If the error persists:
- delete the intermediate and saved folders from your project
- delete and reinstall the ue4 version you are using
hope that helps.
Cheers,
