Yeah, a lack of viral games. Riiiiiight!

It has nothing to do with the long-standing grooming/pedophile scandal on the platform, and their ham-fisted legal reaction to it. Or the overly draconian and poorly-implemented age verification checks. Or their push to turn Roblox into a dating platform. Or any number of other stupid strategic decisions they've been making.

ETA: Interesting insight from my kid. Fewer new games are making it on to Roblox because of the stupid age restrictions (you have to be she verified to use Studio), and the fact you now have to pay 1,000 Robux to publish a game, and you have to get a certain number of 16+ users to sign in to our like your game. So naturally fewer viral games are appearing, because they've narrowed the wider new games spigot.

Basically: Roblox hurt itself in its confusion.
