Universal Links is an Apple protocol - it acts as sort of a "middleman" in DNS lookup/routing - it is a pretty large database, a list of websites.
It could be the "server" that it is on - or the database itself - reading it every link tap, from whatever app, causes your device to get caught in an "infinite loop"
