“The food in the crock pot must be completely cooked or completely raw -i.e. -the raw food should be placed in the pot as close as possible to Shabbos.”
What happened to Muktza? How can you eat this food?
The food was put on the fire before Shabbos, so it’s not muktzah. In your case, since food was not on a fire, and it’s assur to ask a nochri to cook it, it’s muktzah.
I’m not sure why you needed to quote the PHS; this is the basic halacha of “kidra chayso” in S.A. 253:1.
