Megalomaniak Directional shadow framebuffer status invalid Quoted error makes me think there might be a node of the 3D/spatial variety in your scene causing the error such as a directional light perhaps?
Ace_Dragon I would report console errors in release builds to Godot's issue tracker on Github, as it may be an indication of a bug (even if it's not so visible to the user). Don't forget to provide information about your GPU and the drivers it has.
