Game is crashing when level streaming with Async Loading screen.

Development Programming & Scripting

Almost done working on a simple horror game project. I have never did Level streaming before… While transitioning from Main menu to Gameplay level I am using Level streaming to load everything up… but It’s now crashing :frowning:

(when I am not using async and directly opening the level the crash does not happen)

Here is the full error:

Assertion failed: !PackagePath.IsEmpty() [File:D:\build++UE5\Sync\Engine\Source\Runtime\CoreUObject\Private\Serialization\AsyncPackage.h] [Line: 66]

Found the solution… In the Levels tab Right click and convert whatever Level was causing crash to External actor
