Some people have reported many bugs Resolve had with various hardware. The latest Resolve updates should have sorted that out (you downloaded the latest version?).
The iGPU should be inactivated, as CaseySJ indicated, as an active iGPU can make Resolve less stable.
The 475% CPU usage you report is a little bothersome. It should be more like 80 to 95% during max use. I may have missed it, but are you over-clocking? If so, perhaps lower the settings. (If at 5 GHz, maybe try 4.3 or 4.5 GHz.) And, have you set the AVX in BIOS to something like 3, rather than leaving at Auto? That might help.
In looking at the DaVinci spec requirements (here), you should be fine. In the preferences section, you can specify how much RAM is used by Revolve. I've also heard that selecting DNxHR SQ in the optimized media preferences section may help reduce CPU overhead (but at a cost rendering time and storage space).
Are you over-clocking the RAM? I've seen stability improvements by decreasing the DDR4 speed, in 200MHz steps, from the maximum rated speed. The overall loss in computer speed by the reduction is trivial vs the potential for improved stability.
Another source for Resolve crashes in inadequate file permission. Maybe give Resolve full access permission in System Preferences/Security & Privacy/Privacy/Accessibility section. And also check the permissions of the folder where files are being read and written to: highlight folder and right click for "Get Info". Then, at bottom of this window, allow "Read & Write" for all users.

I'm back in the studio after my vacation.
I tried setting the AVX in BIOS to 3 and it's still crashes on render. I've also try setting 0 with the same result.
Sometime it crashes at 2%and other time at 50 to 80% point, very random. I also tried rendering to different codec.
When it crashes, it will lock up the machine and the only way out is to reboot.
Permission on disk is set to both read and write and I have also try rendering to other hard drive.
Resolve has full permission in System Preferences/Security & Privacy/Privacy/Accessibility section.
There's no OC on CPU and RAM.
I have 32GB of RAM and have limit Resolve memory usage to 24GB.
I'm using the Studio Version of Davinci Resolve 16.
