There are no examples of irreducible complexity, just the claims. I think the scientific community is done doing that. I know of several biological systems offered by cdesign-proponentists as irreducibly complex that were debunked - eye, flagellum, clotting cascade, and immune system - but I imagine that the scientists are just disregarding these claims now. Bare claims don't need debunking.
I did explain my point about irreducible complexity in #5999. You didn’t pay much attention and simply ignored everything I said. You may go back and read it.

Lets keep things simple, the main point is specifically about
“survival”. If the organism doesn’t survive, it doesn’t evolve. “Survival” is a product of numerous interdependent functions, if you take a system out or only a key component of a system, survival wouldn’t be possible (irreducible complexity).
For example, an animal that has all required complex interdependent systems for survival but missing only the “Epiglottis” or maybe something simpler such as the “Anus”, how long it would survive to somehow get one through some random means? The animal simply would neither survive nor evolve.
Now let's touch upon another less tangible aspect of life, which is the “psychological characteristics” such as feelings, awareness, and behavior. Assuming that the animal somehow got all necessary physiological functions but doesn’t have a feeling/desire to feed or maybe feeding causes unpleasant/painful experience, the animal would neither feed nor survive. If the animal can feel the need/desire to feed but doesn’t have the ability of input processing/decision making, it can neither feed nor survive. If it doesn’t have pain awareness, it will not survive. If it doesn’t feel a desire to mate, it will neither survive nor pass changes to offspring. Survival is contingent upon all necessary psychological and physiological systems being functional from day one (irreducible complexity).
The alleged gradual change/transitional forms is a myth (nonexistent in the fossil record). Generally, whether the entity subject to the alleged gradual change is an organic molecule or actually a living system, survival/persistence is an absolute prerequisite before any gradual change of any kind may emerge/materialize. Neither a living system can survive without the vital functions from day one nor a biomolecule can persist for a long time without getting decomposed/disintegrated. If survival/persistence of a system is not possible, then no evolutionary process of any kind is possible
Only a perfect organism equipped with all required vital functions for survival from day one may persist and adapt (through directed mutations, see #1245). What we witness in the real world is directed adaptation not random microevolution. The hypothesis of macroevolution is false.
