Well, I don't think you're doing anything wrong -- I think it's because you aren't using any preservatives in your bread (and that's a good thing, right?). I find my homemade bread has to be eaten in ...

My sourdough starter is going wrong in every possible way

If it has mold on it then it needs to be thrown away, you are unlikely to salvage it. Once a sourdough starter goes wrong it's generally not worth your time to try and save it, just start over.

Is this layer on top of my fermented peppers mold? If it is not, is it still safe to eat?

The growth of yeast is already slowed down by the approximately 2-3 bakers percent salt content in a dough, which makes round about 1-1.5% in total. So I doubt yeast will grow on a brine with 10% salt ...
