One solution for the ending would be if they advance the simulation by a couple trillion years in an instant. Then the layer below them, and very likely themselves, can feel safe that their universe won’t just end because the computer above them turned off. Then they can go and behave as if they’re the top-layer, as they will be for subsequent simulations they perform.
The one downside is that they then can’t expect any help or benevolence from the layer above them, but in my opinion if you realize that your universe is being simulated on a 1 week-old experimental processor, you should want it to finish simulating your universe’s remaining history asap before it breaks down for whatever reason.
And more recklessly but beneficially it could be advanced slowly (at first) forward and observed. Especially if they could code up a recording feature for later review.
But definitely run it out to infinite time before leaving it alone.
Spoiler - enjoy story first

Yeah, I had that thought too.
