No mention of this game in that dxdiag. But lots of crashes in MsiExec.exe , do try unloading all MSI apps/utilities and geForce Experience if running. And undo any overclocking you might have enabled.
Well, I assure you that is a problem with this game and those models of CPU. Also with Vic3 and Imperator, that use the same game engine.
It may be you have a different problem as well, or instead, of course. However your symptoms do match the problem with e-cores ... are you sure you've set Affinity correctly for ck3.exe and your setup?
DXDIAG is a program you run from the Windows search box on the task bar. After running it will open a window and start collecting info with a progress bar in the lower-left corner. When it completes click the 'save all information' button and save it to a file then attach that file here.

From your Documents/Paradox Interactive/CK3/logs/ folder, attach here system.log , error.log
