Good clear pictures of your machine situation are always helpful. You never know if someone sees something you have overlooked or we can compare how it is set up.

Usually a needles brakes when it hits the needle plate.

Your needle plate has 2 different sizes of needle holes, try the larger hole and try to center the needle or set it a bit more left instead of centered.There are also 2 different needle plates available one with smaller and one with larger holes (both have 2 different size needles holes for different size needles) No matter what I sew I`m always using the the larger hole. The plates work for 29K71 and 29K73 and their clones.

or the needles brake when it hits the hook or the hook grabs the needle and brakes it (I heard of the 2nd issue but never have seen it happen). In both cases I´d say the machine is not well timed. Check the 29K71 / 72 manual for timing your machine.
