Moon Knight Bust Marvel Superhero 3D print model

With the second episode hitting Disney + this week I am totally hooked on the latest Marvel series Moon Knight. This is a bust of the Marvel super hero played by Oscar Isaac.

I am getting a strange non-manifold error, but I can't find anything wrong with it. I am currently running a test print. My cura tends to have this strange glitch where everything appears non manifold, so I am hoping that is all this is.
