Assertion Failed error

I’m in the process of updating my game from Unity 18.2 to 19.2. I am getting the error “Assertion failed on expression: ‘m_CurrentHiddenGameObjects->find(gameObject.GetInstanceID()) == m_CurrentHiddenGameObjects->end()’ UnityEngine.Object:DontDestroyOnLoad(Object)” when loading certain sdks/plugins. (I’ve noticed it from the AWS sdk and from rewired). I don’t know what this means. Can anyone help?

Things appear to be working as intended despite the error messages (ie files post to AWS, rewired menus seem to function fine)
