This seems like a hardware error to me. Please try and boot in the safe mode to see if this problem is persisting


  1. Turn on or restart your Mac, then immediately press and hold the Shift key until you see the login window.
  2. Log in to your Mac.
  3. You might be asked to log in again.
  4. On either the first or second login window, you should see “Safe Boot” in the menu bar.


In the safe mode, external apps are not loaded so if this is a problem caused by external apps the problem will not occur in the safe mode. If the problem is persisting this is most likely a hardware issue with your MacBook. Please Contact - Official Apple Support to set up hardware service for your device
