This is really a question for the bench but ...
thin watery CA glue is the only reasonable choice here. It will wick into areas of that crack you can't even see ... get he glue in there good, clamp carefully with padded clamps (not a ton of pressure).
For absolute certainty you could add a small underlay of fiberglass on the belly side of the tip to reinforce, but it's probably overkill ... plus then you're getting into filing/sanding/refinishing etc.
If you don't wanna screw with it, you could send it to someone .... maybe bow hospital can help.
