Fallout: New Vegas

Steam: Successfully installed

Fallout New Vegas: Successfully installed, but crashes when trying to start a new game or load a savegame.

I have tried all game patches and mods that people have suggested on different forums and blogs, but without luck.

I have manually installed DirectX too, but the game still does not want to load.

Downgrading game resolution and setting compatibility mode to windows 7, 8 or 10 does not work. 

Is there anything I can do? PS: It is a VM created from scratch, windows 11 is updated to the lastest version as of august 9th 2023, the VM has 16GB RAM and 4 CPU cores. I also added about 8GB graphics memory.
