Are you using a Rii mouse/keyboard by chance? If so that is what is causing the shutdown as I unplugged mine and it no longer tries to shutdown.

Have this issue as well but on windows 10. Running v12.14 on 3 different drives and computer shuts down on 2 of them, didn't have this issue before. If I boot up game directly from drive without using bigbox/launchbox it does not shut down/go to sleep Update Fix: Running "Don't Sleep 8.91" softwareand checked off the 4 blocking preferences in the don't sleep tab (standby/shutdown/turn off monitor/logoff) Launchbox seems to working fine with no interruptions. BigBox however randomly will switch to a blue screen trying to shut down. After hitting cancel and it goes back to where left off.
