[2023] Game crashes on launch with exit code 3221226356 on a windows 11 pc

No mention of stellaris.exe in that dxdiag. What happens if you run it manually from File Explorer, any Windows error show then?

Our similar game Crusader Kings 2 is free to play on Steam now, does it work or have a similar problem?  

No real idea then ... what if you make a new Windows user and log into Windows with that? Do you get the same problem?  

We've seen devices like joysticks and Xbox game controllers cause this, but not Razer gear up until now. All I can really suggest is to check with them for updates drivers, as most of yours seem to date from 2022 at present.

Good luck!  

Has this game ever worked on this machine?

What happens if you run stellaris.exe directly from file explorer?

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.
