Client closing without error message

[HappyIdiot]

Hello guys,

since a few weeks the client is closing itself in like every third game. There is no error message or anything. It only happens while in a game, not in a lobby. I lose connection to all players, minimize the game and see that the client is gone and not running anymore. Any ideas what could cause this and how to fix it? Logs are attached.
