That's on the Intel defect list. So regardless of whatever else you're doing, make sure you have at least the microcode version 0x12B or later as mentioned at https://community.intel.com/t5/Blogs/Tech-Innovation/Client/Intel-Core-13th-and-14th-Gen-Desktop-Instability-Root-Cause/post/1633239 [community.intel.com]

well I have installed the latest bios and chipset software availble on day 1 (Pc is about 2 months old) but for safety (thanks for the links and post) I double checked

and it shows I have version 12B not sure how I can version up this but it appears not to be the wrong version I hope.

so if you have this latest bios / chipset updates installed as Edward's post details and links above and still crashing with segmentation faults on a new build - check your device drivers for errors!

also. I had a few more Segmentation fault crashes when changed some settings on the pyro OUCH! so deleted preference. Nope. installed the latest production build 20.5.487 (from 20.5.445) and it seemed to have got past the segmentation faults from where previously it was crashing.

FIngerts crossed its stable!
