Last vanilla update is 2.0.1 (1203).
To help me to resolve problem, remove "Logs" folder, update WRobot, disable all plugins. Try to run, if you don't get crash try to enable one plugin and try again, reenable plugins one per one (you can also try to change your profile/fightclass) (you can also check if this problem happen only when you launch multi wrobot sessions with the same key). When you crashes, don't forget to share logs here (or if you found the plugins/fightclass/profile that can cause this issue).
