Judging by the picture you have Windows 7, due to the fact that the game requires Directx 12, you need Windows 10 (the last stable 20H2), oh, and besides, the video must support Directx 12 at the hardware level.

Updates seem to be all worth it, how to put 12 dx on the seven?

Vidyuha supports 12
In the case of the game World of Warcraft: Battle for Azeroth, the T-shirts and the developers collaborated to port Directx 12 for this game to Windows 7, for other games this was not, it seems that CoD Warzone works on Windows 7, the T-shirts and the developers also collaborated to port, it seems that T-shirts have been created for them with a limited toolkit for porting, at least Windows 7 needs to be with all updates including SP1 and updated Directx components (although Directx components, Directx 12 are not included), and Directx 12 for 7 as a crutch, not all functions are available in Windows 10, but about Assassin's Creed: Valhalla, I'm not sure that the game will start on Windows 7, so either measure it or not fool yourself and finally install Windows 10.
