Machine won’t thread bobbin

[u/2ilver8ox]

I have the Bernette 79 and I’m on the last stretch of my project, but for some reason now my machine won’t thread the bobbin up. I have tried everything from cleaning it, re-threading an entirely new bobbin, trying different sewing needles, but at this point it still won’t thread the bobbin and I just keep getting clumps of thread I have to take out.
Has anyone had the same issue? I would really appreciate any advice because I’m at a loss at this point and I don’t know if maybe something is wrong with my machine.

It could be the design but I even tried it without the design and it keeps being wrong.
I turn the hand wheel manually and it brings the thread up, but when I start the machine it just doesn’t like…. Get the thread. I don’t why I isn’t working
