How many RPG cons out there are struggling with negative or stagnant attendance?

This post was inspired by my recent experiences with different cons. To the best of my knowledge, all of them are growing in attendance. I'm a relative latecomer to the con world, having started with the virtual GaryCon in 2020 and attended my first in-person in 2022, but I believe all of them have reported growing.

Are there any out there that have been struggling with declining or stagnant attendance?
