Segmentation Fault on Linux VKRT build.

[YTJVDCM]

ArmorPaint version:

858e402
(also happened in the official alpha 1.0 binary)

OS / GPU model:
ArchLinux x86_64 kernel 6.12.8-arch1-1
Radeon RX 7900XTX
(RADV 24.3.3, AMDVLK 24.20_2044449)

Issue description:

ArmorPaint crashes with "signal SIGSEGV: invalid address (fault address: 0x0)".
I tried the open source version of the driver (RADV) and AMD's proprietary version of the driver (AMDVLK), both of which failed.
GPU driver and GPU supports Vulkan raytracing because raytracing example of this worked successfully.

Here is the backtrace information I got from LLDB.

Steps to reproduce:

1. Clone this repository.
2. Move armortools/armorpaint.
3. Run ../armorcore/make --graphics vulkan --run
4. Segmentation fault
