This is a longer trend with the way women behave online. Ghosting, zero-effort one-word conversations, setting up dates and then backing out last minute. This describes 95%+ of my online interactions with women since around 2016 or so. This is coming from someone who used to consistently get 1-2 new dates a week before eventually finding a very long term relationship with a girl who met me for a drink after I asked her out in my second message. My suspicion is that some sort of attention tipping point re: female psychology has been reached - they're so inundated by everyone that they want no one.
