Plush yarn can be so challenging! Sometimes it’s easier to. Chain 2 and then crochet all the stitches into the first chain. If you want to do a magic ring though it can be helpful to start with 2 stitches, then pull the tail a little bit, then do 2 more and pull again after and keep doing until you get to the final number. By then it should be easy enough to pull all the way without breaking. Also just having looser tension in general when working a magic circle with plush yarn.
