Can someone PLEASE help me figure out why this happens? I have an industrial sewing machine- Jack A7

I’ve changed everything I know to change.
Foot is up when threading.

I have read somewhere to keep the thread in the back when starting to sew, but when I do, the upper thread breaks immediately every time. This happens when I use back tack or not.

Thank you for any advice 🙏 I’m going a bit crazy over here.
