Why can't I select an object that's inside the level from my gamemode blueprint?

Hey guys in the two photos i posted I’m trying to equip an object from the game world using a UPROPERTY actor variable inside my GameModeBase custom script. It shows an object in the drop-down menu but I can’t select it? I even tried using the tear drop to select it directly in the world but it still doesnt show up - just displays “None”
Thanks guys, any help would be great!

The instance you wanna to point would be created after begin play. Thats why you cant assign it during BP construction perid.

Try assign it dynamically in BeginPlay
