2018 Macbook Pro keeps crashing

My 15inch MBP keeps crashing and sometimes it is successful in restart. Sometimes, it fails and all I see is the Apple logo coming and going off, with fan running at high speed for 2-3 seconds.


I have tried re-installing the OS 3 times, completely formatted the laptop and still i face this issue.

I have seen related issue posted, but could not see any solved threads.


Would be great if someone could mention the fix or anything that helps.

MacBook Pro 15”, macOS 10.15

I had taken it to Apple store for diagnosis. Prior to giving the laptop, I had changed the OS to Mojave. They did their diagnosis for two days and returned the device saying hardware is working fine. Now the laptop has started crashing again. This is really frustrating when such an expensive device starts abnormal behavior in 1.5 years.


I am attaching the entire crash report in additional text.
