Game won't launch after update

[Avallach]

Hi, I have played over a 100 hours, but recently I updated my Windows 11 version and now if I try to launch the game it doesn't start and it displays the message:

DX12 is not supported on your system. Try running withput the -dx12 or -d3d12 command line argument.

What does that mean? It was working fine before. How can I fix it?

Thanks

Did you check update of your graphic driver? Otherwise click with right click on the game in Steam, go setting. You see grey bar below "Start option". Put -dx12 into the bar.

Updating worked
Thanks!
