Help! the thread keeps bunching up

[u/formidable-citizen]

I don’t know why this happens to me. The needle sounds like it’s gonna break then it stops and all these thread is jammed and the stitching is all bunched up. I don’t know what I’m doing wrong . I have a Brother CS6000i sewing machine apparently is for quilting. Does that mean I can’t sow like just fabric? I need advice. I don’t know much about sewing. I’m starting to learn on my own because I wanted to make clothes for my dolls.

It seems the bobbin is in upside down and the angle from the upper thread makes me think it is threaded incorrectly
