This might be a bug. Is your problem solved now? If the problem continues i would advice you to contact apple support Asap. Make sure u have good Antivirus software which is necessary for Macbook maintenance. I have wrote a article on Macbook maintenance on https://www.ttricks.com/how-long-does-a-macbook-last/. Know how long does a Macbook pro last.
