I have the same issue.

This worked for me. Thanks BrandonW87!

I did some research. calling publishedServiceRecord on Ventura with any 16bit uuid in ServiceClassIDList WILL crash bluetoothd. This will disconnect all bluetooth devices (keyboard, mouse, headphones, watch etc...) from the Mac and then reconnect. This problem does not happen if you are using a 128 bit UUID. This seems to be fixed in the Public Beta of Sonoma.
