So I looked at the definition of clickfix patterns in uBlock and all I can think of is that some link contained one of the generic patterns in there, like .com/api/users*^pii=&in=false^$doc, or one of the hardcoded element IDs like #turnstile[onclick="handleClick()"] - but if it were to work properly, that should have been triggered in the arena.ai site too?

Was there a URL in your text?
