In packaged build (windows) I got a crash when colliding with elements from a Geometry Collection. I never got this error while playing in editor.
Here is the log crash :

I have tried with differents GeometryCollections that I have generated, and the bug/crash is consistent.
Dont occur when colliding with anything else but systematically with collapsed elements.
Okay, I managed to found it.
It is when the capsule of my Character (player) collide with the GC.
I changed the collision settings for the GC Component to not be overlap anymore but ignore :
And then I dont crash anymore.
I still dont know why this cause a crash in a packaged build and not in the editor.
