[2020] CK3 Crash after Loadingscreen

Has the game ever worked? Or never yet?

DXDIAG is a program you run from a command prompt or the Windows start menu 'run' dialog box (or 'search programs' in Windows 7 or later). 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 your Documents/Paradox/CK3/pdx_settings.txt .
From your Documents/Paradox/CK3/logs/ folder, attach system.log , error.log  

Please update that AMD video driver, it's 5 years old. The May 2020 one from here is good:

All the best!

You have a severe memory hardware problem:

Memory: 10240MB RAM
Available OS Memory: 2014MB RAM

The game will not run in 2gb of memory. You'll need to get that fixed .

You should also update that AMD video driver:
