If you have a campaign save that was started under 1.9 and has never had any mods used in it, does it trigger these crashes fairly reliably?
And let's have a look at 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.
Please attach here your Documents/Paradox Interactive/CK3/pdx_settings.txt .
From your Documents/Paradox Interactive/CK3/logs/ folder, attach here system.log , exceptions.log
