Instant crash on startup on AMD GPU

[GarlicBread]

Game Version​

2026.10.7.5541

Operating System​

Windows 11 Pro 64-bit (Build 26200)

What Happened​

The game crashes instantly on launch before displaying any window or loading screen.

Looking at the generated log file, an unhandled exception occurs during Vulkan renderer initialization inside `RenderCore.Systems.BindlessTextureLibrary..ctor`. The AMD Vulkan driver returns UINT32_MAX (4,294,967,295) for `maxDescriptorSetUpdateAfterBindSampledImages` (indicating no driver limit), which appears to be signed-cast into `-1`. The engine logs "Device supports only -1 update-after-bind sampled images per set; bindless texture capacity reduced from 1024" and then crashes with `ArgumentOutOfRangeException: Non-negative number required. (Parameter 'capacity')` when allocating the internal pool list with capacity -1.

What Was Expected​

he Vulkan renderer should handle the unlimited driver property without signed integer underflow, initialize the engine, and open the game window / main menu.

Reproduction Steps​

1. Install KSA build 2026.10.7.5541.
2. Launch KSA.exe on a PC with an AMD Radeon GPU (e.g. RX 5700 XT).
3. The process terminates immediately without rendering a window.

Reproduction Rate​

Always (100% on every launch)

Additional Info​

Hardware Specs:
- GPU: AMD Radeon RX 5700 XT 50th Anniversary (Driver: 32.0.21045.5002)
- CPU: Intel Core i9-11900KF @ 3.50GHz
- RAM: 32 GB

I can confirm the same error happens on Linux with RADV and AMDVLK drivers.

Same crash on a different AMD card, so this does not look limited to the RX 5700 XT.

GPU: AMD Radeon RX 7700 XT, 12 GB
Driver: AMD Software Adrenalin 26.9.2, clean install. Same crash on the previous driver 32.0.31019.2002 (dated 2026-05-29).
OS: Windows 11
Game: build from 2026-10-02, installed from the official Ahwoo installer.

Every launch dies at the same point, before any window or loading screen. Latest log:
