Couldn't start the game?

[Rify]

I couldn't start the game upon patch 1.01 being released and get a CreateProcess() 570 error upon hitting the "start" button in steam.

Not sure how to post an image of the error itself but it says:

Couldn't Start:
"E:\SteamLibrary\steamapps\common\S.T.A.L.K.E.R. 2 Heart of Chornobyl\Stalker2\Binaries\Win64\Stalker2-Win64-Shipping.exe"
Stalker2
CreateProcess() returned 570.

Any ideas as to why this is happening?

CreateProcess error code 570 is new to me, though it's as always a permission error one way or another.

Check your antivirus, remove compatibility flags from executables, etc. and verify game files in Steam.

I had the same problem. I solved it by checking the integrity of the files in the properties

Launch Steam via Run As Admin.
Library > right click STALKER2 game > Properties > click Verify and allow this to finish.,

Set both STALKER game EXE to:
> Disable Full Screen Optimization
> Run As Admin

If you have 2 GPUs, go in to WinOS Graphics Settings, add both STALKER EXE files to the list and change each Options to High Performance GPU.

If you had ran this game before, dump all your GPU Shader Cache from these locations:
> %LocalAppData% > AMD or NVIDIA folder
> %LocalAppData% > STALKER2 > just the shadercache file there.

If NVIDIA GPU, set these in NVCP:
> Power = Prefer Max Performance
Shader Cache = Unlimited

If have not already, disable these in Windows Defender:
> Core Isolation
> Controlled Folders

Might help to add /Steam and /SteamLibrary to the anti-virus Exclusions listing to avoid needless real-time scanning of such folders, which can slow down game loading, or even cause in-game stutters.
