If you do a quick search on this forum, you will find countless posts like your own, from hosts who don't understand why their bookings have slowed down or stopped altogether.
There are no doubt a number of factors that could be contributing to this, including the current economy. However, most of the other responses seem to ignore the enormous elephant in the room, which is Airbnb's recent and drastic changes to its search algorithms. This started with the Summer Release and introduction of categories in May, followed by the Winter Release in November (search from them here) which have decimated views and bookings for thousands of previously successful hosts. You will find hundreds of comments on this forum about this if you search for them.
On top of that, you have a large increase in supply, i.e. more listings on the site, but the demand, i.e. nights booked, has not kept up with that. Although Airbnb has reported its best quarter ever apparently, what it fails to mention is that those bookings are spread out over a greater number of listings and, yet, it is relentlessly pursuing new hosts to broaden supply. Let's face it, Airbnb doesn't care which listings guests book as long as it gets its commission.
As for your listings, yes, you have lots of wonderful, glowing reviews. But, the overall ratings on your listings are not that great. I see that you are a Superhost so I don't know what your ratings are in the past year, but Airbnb requires 4.8*+ for Superhost and 4.7* is supposed to be the minimum acceptable standard, and your listings are below the latter. I totally understand what you are saying about issues with post pandemic guests. I have certainly experienced similar problems and my ratings have suffered as a result. However, there are some complaints in your reviews which reoccur and seem to be mostly to do with the outside spaces such as the pool and the garden, so maybe I would focus on those and see what you can do to improve them.
I would certainly follow the suggestions to list on other sites. Even if Airbnb has been the best for you so far, it has changed a lot in recent months (as has the market), so now is not the time to be putting all your eggs in one basket if you can help it.
