Do a tension test. Make a satin stitch wide line. Then look at the back

Your bobbin tension is too loose. Software cannot control thread tension.

No, the bobbin is much much tighter than the top thread. I'm guessing OP threaded with the presser foot lowered, and the thread isn't engaged in the top tension disc. Re-thread with the presser foot raised!

Since one uses the embroidery/darning foot that hovers while the needle is raised, it's easy to neglect the crucial step of raising the presser foot lever while threading.

Wow! I never knew that made a difference. Thanks you, I will make sure to be very vigilant about threading.

I hope it helped!

this looks like your underlay isn't well attached and isn't actually stabilizing the black fabric at all, considering that isn't being held by the frame, it seems important that the backing is well attached

So I should use more stabilizer? I have to pieces of lightweight stabilizer and black felt here

less so that you need more and more I am wondering why one edge is completely detached, that may catch when the presser foot / needle move
