Hi @Genevieve346
I have seen some other hosts in the US mention the same issue on this board, and some hosts replied that the economy has slowed down and that there are more short-term rentals available these days.
From your side you can just check that you haven't perhaps done anything unusual to your listing that is making it harder for people to book. Check your minimum stays and trip rules and restricted check-in/check-out days. It's good to go in as a guest to dates that you would like someone to book, and to check whether your listing shows up - I have seen my own listings not showing up many times, because of restrictions that I had forgotten about!
Also, if you are now getting bookings from other sources for the first time, you could have fewer bookable dates on your calendar for Airbnb guests. This can perhaps count against you a little bit in rankings (depending on how many competing Airbnbs there are in your area).
