UE 5.3.2 Build fail using Plugin v4.12.0

[Luca71]

Please find attached the issue from my build output log. I'm not using hands in scene, only an actor with Leap component attached to move an object around the scene.

Hi, please can you update the plugin that you are using to the latest version and retest?

https://github.com/ultraleap/UnrealPlugin/releases/tag/v5.0.1

If the issue persists please can you let us know and we can investigate further.

Hi, Before your reply I resolved the issue transforming the UE project in C++ project adding new C++ empty Class. Then I compiled the project from visual studio, and now I'm able to build succesfully.
