If this abort() is unexpected, build with -s ASSERTIONS=1 which can give more information.

Hey ,

In order to better assist you, would you mind providing me the project through a private message on the forums? Also, did you create your project through the editor obtained through the Epic Games Launcher or through GitHub? Also, could you show me how you’re pulling up your game from your local HDD?

Thanks!
