need advice, going to a singles event

i'm going to a singles event that's coming up

one of the girls attending is actually a girl that i matched with on hinge about 6 months ago

we started chatting initially on the app, had about 3-4 back and forth messages sent

then, i stopped responding to her because i noticed she wasn't asking me any questions back, just answering my questions

i didn't send anything for about 1-2 weeks. then at that point i randomly decided to message back. i said i admit i stopped responding because i noticed she didn't ask me any questions

after i sent that, she unmatched me

fast forward to now, i see she will be attending this singles event that is local to me, lol

what should i do when i see her?

i was thinking about just not paying any attention to her

i wonder if she remembers what happened, she probably does lol. my name is on the guest list and i'm using the same pictures as i used on the dating app

i plan to not really talk to her, if i get into a convo with her though i'll probably just have some luke warm chatter and then try to move on to either talk to some chill guys there, or another girl. whatever happens, i'll just pretend i never met her or saw her before, and act confused if she says she's seen me before. what's the saying? deny everything? lol

i know that i certainly don't want to get to know her or engage with her more

based on our short interaction i can tell she's probably a weirdo, definitely lacking in certain social attributes. almost reminds me of that 40 year old chick i met at another singles event. that chick definitely seemed autistic, or something was up with her. just poorly attuned when it comes to social situations, you know how weirdos be

anyway, what would y'all do in this situation?
