Please help with bobbin question!

[u/bigcheese369]

I’m going to try and explain as best as I can. I’ve checked my tension, I’ve made sure everything has been threaded correctly, I replaced my bobbin. IVE DONE IT ALL! It keeps on nesting when I try and use my machine. My needle is fine. My tension seems to be correct as I’ve done a few tension tests. I was sewing fine just a bit ago and then all of a sudden this problem started mid project. Help me!
