so let’s say the alpha kids were just in their OWN session with just themselves and no beta or troll kids would they fail considering non of them are space or time players? and what would happen to their session if they didn’t prototype anything (while being the only ones in their session) would they just be stuck?

They’re not even a viable Session to begin with, the Alpha Kids didn’t prototype anything. They’re in a 100% unwinnable Session. The Kids at least had everything set up to actually have the possibility of winning. So yeah, stuck.
