That “gradual decline” is an artifact of your maths, in which you're gradually changing the weight of recent years.
Consider a sequence with an extreme drop-off: 100, 100, 100, 100, 40. Taking averages of all the numbers, then all but the first, all but the first 2, and so on, yields: 88, 85, 80, 70, 40. That might look like it includes a gradual decline, but clearly there's nothing gradual in the underlying data.

I still don't see a step change. 2022 was bad, but not as bad as that slump in 2015-2016.
The Simpsons had far too many seasons, but Matt Groening eventually went on to create Futurama. I hope you figure things out.
