Basically, I have a blueprint class derived from UItem which is derived from UObject. I create this blueprint class in the constructor of an actor like so

Item = ConstructObject<UItem>(ItemClass->GetClass());

When I press play, everything seems ok, but always crash when stopping.

This is how I declare the property inside the actor

UPROPERTY(Category = "Item", VisibleInstanceOnly, BlueprintReadOnly)
UItem* Item;

Any pointer on what I’m doing wrong here ?

I was getting the class of a class, no wonder it crashed. Changing the construction like the following works

Item = ConstructObject<UItem>(ItemClass);
