mackbook pro keep crashing and reboot itself

In my experience, GPU temps in mid 70s is where crashes begin, & after time at those temps permanent failure sets in.

I can't tell much from Crasj=h Logs anymore, but looks like one of these 3 reasons...

AppleMobileFileIntegrity, is an iOS kernel extension which serves as the corner stone of iOS's code entitlements model. ... The latter function registers a MAC policy (using the kernel exported mac_policy_register), which is used to hook various system operations and enforce Apple's tight security policy.

Or the Graphic card, possibly heat related.

A couple of ideas.

1) I think you have 3rd party RAM.

no map entry at 0xffff0081e74a5000

might be caused by RAM dropping or adding a bit and sending the virtual memory code to the wrong location.

2) Your Mac is of an age that it may be suffering from a failing discrete GPU chip. I have a Late 2011 15" Macbook Pro that has a failing GPU chip. You could try using something like gSwitch and tell the Mac to use the integrated intel graphics

3) You do have 1 3rd party kernel extension

com.intel.kext.intelhaxm	6.2.1

I do not know if that would interfere with the virtual memory management code, or with the GPU. But if you do not need that kernel extension, you could try removing it.
