Can't run Vulkan - Auto reverts to DX11

Hey guys.

I tried to enable Vulkan API today, and it just didn't work for me.
Whenever i try to switch it in options menu it pops-up with a:
Also happens when i try to change it in "production_Config.ini" right after starting the game.
Then it goes back to DX11 automatically.
Tried to google it without a result.

Of course my drivers are up to date with Vulkan 1.2 support

I'm running an -NVidia RTX2060- GPU with -Ryzen 5 2600- CPU


Not a big deal, cause im running smoothly on DX11 but just to let you know. Also please tell me if you need some more logs or sth.

Best regards GGG, keep up the good work!
