QRCodeActor must be on the active map and must be initialized, I just put it in GameMode so as not to add it to the LevelBlueprint on all levels, I don’t know about Ventura, I unfortunately can’t update MacOS since I have a 2015 iMac, it does not support Ventura and UE5 on a Monterey system does not support Xcode 14
so I’m using macOS Monterey 12.6.4
XCode 13.4.1
