I installed the game normaly on C:/Program Files/ with the .NET 9.0.11, but the game wont run at all. I only see white screen and it stops responding right away.
MS Event viewer says this:

Application: KSA.exe
CoreCLR Version: 9.0.1125.51716
.NET Version: 9.0.11
Description: The process was terminated due to an unhandled exception.

at KSA.Program.Main(System.String[])


and then other event

GPU: AMD RX 7900 XT (Sapphire Pure)

I tried reinstall gpu drivers and the .NET 9, but didnt help.
I looked all over the forum tried couple things that people had problems with but nothing worked.

Any ideas? Thanks
 
Hey, could you post your PC info, including AMD driver version to this thread ->

Seems like a Vulkan related issue maybe. Could you add this info from the vulkaninfo terminal program?
(Open 'Powershell' in your start menu, then type vulkaninfo and press enter, and scroll down to 'Vulkan Device')

example:

Device Properties and Extensions:
=================================
GPU0:
VkPhysicalDeviceProperties:
---------------------------
apiVersion = 1.3.277 (4206869)
driverVersion = 551.86.0.0 (2312470528)
vendorID = 0x10de
deviceID = 0x2208
deviceType = PHYSICAL_DEVICE_TYPE_DISCRETE_GPU
deviceName = NVIDIA GeForce RTX 3080 Ti
 
Ok Ill post that info to the thread.

vulkaninfo gives me this response.
ERROR: [Loader Message] Code 0 : loader_get_json: Failed to open JSON file C:\Program Files\NVIDIA Corporation\Nsight Systems 2019.5.2\Target-Windows\x86_64\VkLayers\VkLayer_nsight-sys_windows.json
WARNING: [Loader Message] Code 0 : Layer VK_LAYER_AGAUEEYE_Overlay uses API version 1.1 which is older than the application specified API version of 1.4. May cause issues.
WARNING: [Loader Message] Code 0 : Layer VK_LAYER_RTSS uses API version 1.3 which is older than the application specified API version of 1.4. May cause issues.

Interesting that it does this because the NVIDIA folder with all those files are still there. I found that json it wanted to fetch. But still its an unused vulkan driver. I think I can safely delete it.

Similar issue on my PC, game wont start at all, I dont even see a blank screen.

AMD Ryzen 5600X
Graphics, Radeon RX 7800XT

I will try to get windows event logs.


Vulkaninfo command outputs a ton of stuff, which part would be relevant here?
 
Not just a problem on AMD, I have a GTX1650 and I'm having the same problem.

Ive spent all morning removing anything v Nvidia name attached to it and DDU unnistalled both AMD and NVidia drivers reinstalled AMD drivers completely, still the same. Vulkaninfo does error caused by Nsight thing I dont know how to uninstall it more then i did. I removed any traces of it even from regedit. the DDU does not really uninstall all the drivers. It leaves all cuda and Nsight and physX intact as well as lot of registers and folder everywhere.

I eventually fixed the issue. Turns out when I updated my NVIDIA drivers I forgot to update my AMD drivers (integrated AMD dedicated NVIDIA)
