Latest linux build immediately throws an unhandled exception

[Autumn :3]

Game Version​

2026.3.11.3916

Operating System​

CachyOS, kernel 6.19.9-1-cachyos

What Happened​

Upon running the game from the terminal, it pretty much immediately returns an unhandled exception, doesn't even manage to open a window, or output anything other than the exception to the terminal before crashing.

What Was Expected​

The game running as normal.

Reproduction Steps​

1. Run the game from the terminal. (Command: ./KSA)
2. Game immediately returns the exception.

Reproduction Rate​

Always.

Additional Info​

Full contents of the exception are as follows:

Unhandled exception. System.ComponentModel.Win32Exception (13): An error occurred trying to start process '/home/autumnvleaves/Games/KSA/linux-x64/Brutal.Monitor.Subprocess' with working directory '/home/autumnvleaves/Games/

Executables do not have executable permissions in this archive, easy to fix:
chmod +x KSA Brutal.Monitor.Subprocess

 

[Grug]

This is because the file ./Brutal.Monitor.Subprocess also needs to be made executable, alongside ./KSA. Previously, all files in the archive were executable but with this release their permissions have been (correctly) dropped to 664.
The symlink for libvulkan.so still needs to be created manually after unpacking the archive. If you aren't aware, it needs to point to your system's file which for Debian based distros is /usr/lib/x86_64-linux-gnu/libvulkan.so.1.

Huh, I totally missed that. Would nag about it if I noticed )

Or install libvulkan-dev which contains libvulkan.so (also a symlink). Relying on a dev name for a library is a bug.
