I use my tiniest scissors ( use cuticle scissors that have a little curve to them) and cut the bobbin thread on the back. Then use tweezers to pull the threads out from the front.
Also, lots of Cuties use a Wahl beard trimmer. All brands calls it a stitch remover but I'm pretty sure you can get the trimmers from any of the Big Box Stores.
I saw on Youtube: Peggy stitch eraser, it was not possible to add the link. But perhaps you can find it. It's an eraser used at the back of the design to cut the bobbin thread, and you are able to remove the rest on the frontside. Hope it works for you
Around $60 -80 US and you need to practice with it first to get good at it. I burned/cut right through my material first try and it is sitting in the drawer waiting for me to get up the nerve to try again.
Think I will just make sure I use my tape measure and re sew my design sounds cheaper in the long run
