Still, can you try to disable the Steam overlay for Battle Brothers?
You don’t happen to capture a screenshot as the game crashes, even if by accident, do you?
Do you run any Vulkan-based applications alongside Battle Brothers that you could close? Other games, screen capturing applications or anything?
According to the crash log, the crash occurs in a module outside of Battle Brothers itself, specifically the Vulkan Steam Overlay and Direct Input, hence my focus on this.
