This CTD happens when a deployable (stakes, caltrops etc) are placed on the battlemap, then dragged into a different position but touch a building/wall/item. When this happens the game will lock-up, and after a few seconds windows will pop-up a Atilla.exe has stopped working error box. This happens every single time; if a deployable touches a building it will always and instantly CTD. This has occurred since launch iirc. Given that Atilla is coming towards legacy I hope this can be patched before Atilla is abandonware.
n.b. no mods installed whatsoever
