That looks like the fairly common "fell off the stand and slapped the floor" crack. First of all, let me make a disclaimer than I'm not a luthier, but I think it could be glued and clamped. It's fortunate that the crack is along the grain line. I have a banjo neck which had a similar crack and was repaired with marine grade epoxy. I wish I could remember the brand name. But I would certainly let a qualified luthier take a look at your neck before you start making funeral arrangements for it. Good luck with it. Post pictures of the outcome.

Clamp it up and glue it with yellow carpenters glue, i.e Titebond original. Epoxy glue can stretch. You have nothing to lose.
I have seen similar fixed and did a guitar neck similar.

I much prefer fresh hot hide glue over all the others to fix a crack like this. It's also very important to make some neck cauls to keep everything lined up before any gluing is done.
I once fixed an old Epiphone guitar with a break exactly like this; I roughed out 3 cauls from a block of scrap wood, then wrapped the neck with Saran wrap and covered the roughed out arc in the cauls with about 3/4" of plaster of paris. When the plaster began to dry, I taped the cauls to the neck and had an exact fit that matched the neck's shape. After the plaster dried, I glued some felt to the plaster and they held the neck very accurately.
I mixed up about 2 ounces of violin grade rabbitskin hide glue and kept the viscosity thin. The thin glue penetrated the cracks all the way up with the use of an eyedropper, and after a tight clamping for 24 hours, the neck was good to go with a little clean-up.

Don't try to glue the loosened peghead overlay at the same time. Do the neck first and the overlay second. You might want to use yellow carpenters glue for that job.

Hide glue is old fashioned, but it still works the best of all in some applications.
