Super glue it ............................... Then super glue. some more...
Re tap it and super glue it again, Over and over until you have made new threads .......
Or use a thin strong epoxy like west system 105/206
Or Devcon 2 ton epoxy might work from your local hardware store.
But you need a epoxy that is going to soak into the pores of the wood .....and set up rock solid regardless if you drill and plug the whole and then drill and tap for the pin hole or try to salvage the threads.
The tap witch is about 45 bucks.
You can send it to almost any cue repair guy can handle that some what easy.
I would run a thread in the ask the cue makers section, see who is close to you.
I can also fix it. but make 100% sure the joint hasn't delaminated before you send it to anyone.
