Not good ;-{ Your logic board is damaged!
Sadly, USB-C is not that locked down! Your system will now be the sixth system I have seen which has been damaged by a 3rd party charger. Apples rush has put a lot of peoples systems at risk.
Do you have AppleCare + if you do I would visit an Apple Store to get your logic board replaced otherwise you'll need to find someone who has the skills to fix your logic board or just replace it your self.
