Nap Regression at 13 Weeks

Naps have been relatively good up until ~5 days ago. We generally follow a 1 hr up 2 hrs down, and she’s been pretty great with it. Now we’re on day 5 of her absolutely hating naps. She’ll bark and cry and claw non-stop. We’ve been having to sit next to her until she falls asleep, but I’m worried this is the wrong thing to do and teaching her we will stay with her for her to fall asleep. But as of now nothin else has worked. I’ve tried going in so she can see me, then leave and come back 5 mins later. She’ll cry and bark the whole time. We’ve let her go 20 mins straight and she doesn’t let up. Any advice on how best to navigate this?
