NativizedAssets is a plugin generated from blueprint nativisation for packaging purpaces. Blueprint Nativisation should add plugin dependency same way as it does with module, so it is a bug in Blueprint Nativisation that causing this warning and it a risk for potential packaging errors. I meet another user on discord that have this issue and point me to this post. So i move this to Bug Raport.
Warning it self in this case can be ignored as long as proper plugin is packaged
