Give her time.
Yes, it could be a red flag. But not necessarily. She has just arrived - new country, new language, new family, children she doesn't know yet, rules she isn't yet familiar with, no real friends yet, a schedule she has never worked before. Depending on where she is from she is probably still jet lagged (and most likely she didn't get a lot of sleep during the workshop). Being homesick is totally normal. The first few weeks are exhausting for most APs. Being overwhelmed? It is a lot to take in! Some can hit the ground running, some need time and some burn out.
It sounds as if your AP needs support right now. Not pressure. Not "Well, AP 1 only lasted a month. I don't think you have it in you with how you are acting on day 1."
Give her a week. Let her do her thing the weekend to come (doesn't matter if she wants to sleep all day or meet up with other APs to make new friends). Schedule a meeting for Sunday night (or Monday morning) to go over the next week, readjust her expectations, redirect where you noticed she is not yet up to speed. And then give her a second week. And see how she shapes up. The adjustment period is different with every AP.
