MacBook Pro Kernel Panic

Hello everyone. I purchased a 2018 MacBook Pro 15 just a few months ago and I am experiencing random reboots. It mostly happens while being on a video call on Skype ( ether using Skype app or web app) or Duo web app.


I already reinstalled Mac OS using the internet recovery and updated to 10.14.6.


I am attaching the report of the kernel panic. Any ideas?

Hi,

Kernel panic log is stored at /Library /logs/DignosticReports/

please post whole kernel panic log here.

Also check your MacBook Pro with Apple Diagnostic if it reports something.
