4.15.1 Crash on packaged game close. MallocBinned2.cpp

Hi ,

Thanks for the reply! I’ve been doing all sorts of builds today trying to gather as much information as I can.

  • The crash does not occur in other packaged projects. Tested with and without the Third-party plugins enabled.

  • We pretty exclusively use the Widget Components in world space render mode. Don’t know if that will make a difference. It seems the widget components handle self clean up pretty well.
    However, I added a Shutdown UMG clean up function that found every UMG widget, checked if it was valid, then called “RemoveFromParent” prior to shutdown.
    I also tried setting the project’s startup map to a new empty level. (Nothing should require any UMG to be loaded). Still fails to close properly.

-Here is our log

*Note : Wwise like to throw the Unload Bank Failure error message and has done so since they moved to the plugin version (4.12 maybe). It has never prevented proper shutdown thus far. Tested Wwise with a sample project and it logs the same error but shuts down properly (using the same engine).
