Error when building: m_SystemData.empty()

I googled for this error, I found a topic about it in Unity forums but I couldn’t fina a good solution. Whenever I build my game, I get the following error in the console:

 m_SystemData.empty()
 UnityEditor.HostView:OnGUI()

To the best of my knowledge, everything works fine in my game, I’m just not sure where this came from. The error has no further details that I can see.

Anyone have any knowledge of this?

Restart the unity
