it spawns map clone but you can see it only on open-space maps

GSChaos has crash handler so it intercepts any crashes from any DLL in game (engine, client, server, GameUI and so on). Check if your game is valid or just switch branch to "steam_legacy" (or vice versa). I and some other people didn't have any issues with Options menu.

when clicking the options menu? it's not chaos mod issue because it doesn't do anything with game ui. bar disappears because of "Disable Chaos UI" effect and it also doesn't work in game menu because it's part of HUD (if chaos_draw_as_overlay is disabled)

I'm developer of GameUI module. All these "trojan" codenames like "Wacatac.B!ml" are generic and it could be false-positive. GameUI.dll is adaptation of Game UI from Alien Swarm (Source) with own mod-specific features/changes. It's 100% safe. Antiviruses see this module as a virus because of protection from rippers (who want to use this menu in other mods). DLL is packed but doesn't contain malicious code so it's like "Trojan:Win32/Wacatac.B!ml". I don't know how to minimize this false-positive nonsense without removing protection stuff from module but I guarantee that GameUI is actually safe.
