PMDG 777 no power after APU shut down on start up

After start-up all engines running fine and I turn off the APU as usual. But since I fiddled with the failures and fluids settings, the whole plane will shut down, like it has no power source, even though the engines are running fine and the generators are on?

What am I doing wrong? As far as I know, I do not have to turn on/off any generators in the 777, it’s all auto?
