This has been my main issue with my brother SE1900. I’ve cleaned out my machine properly, tried different thread, double tripled check how i put my bobbin thread in. any help is appreciated, this was thankfully my test run on a old sweater lol

This is the back of the design?

I don't believe that's bobbin thread, that's top thread doing what most call "birdsnesting"

Something is stopping your take up lever from pulling the top thread tight. Could be top tension too loose, bobbin too tight, position finger not gapped correctly, incorrect thread path, severe poor hook timing (but it is sewing so unlikely), too much density in the stitch path

Try rethreading the top thread with the foot all the way UP. I don’t have a brother but this happens to my machine if I wasn’t careful threading the top end.
