I read online that there was a scene after the credits of Halloween 2018. I stayed until after the credits and only saw a “Universal Parks” logo and that was it. Was there ever an after credits scene? Did anyone see one?
Not a scene, you just hear Michael breathing.
You just hear Michael Myers breathing. Most likely indicating that he survives the fire leading to a sequel. You cant kill the boogeyman! 
Ah man, I never heard it.
