Keen Sudoku soft-lock

I’ve gotten to this point after a long time of staring. I know an 8 must go in one of the boxes with the star. I also know that in the right two boxes connected to the upper star, there is either a 7, 8, or 9.

Other than this, I can’t find any other information to definitively identify a box.

In my experience there is always some logic that could be applied to solve a sudoku step by step and there should be no guesswork. Is this belief false with KEEN. Is it always false?
