This has been happening since yesterday’s outage.
I have been working on a certain game for the past few weeks, and just recently I have not been able to join the game. Even when other players are not in the game, it refuses to allow me to access the game through studio. It is just with this game, no other.
Yesterday I was able to get this to work by having everyone else leave the game and then I restarted my computer, and it gave me no error and let me in. However, now no matter what I try it will not allow to access my game.
Later I found out that this is not only from my PC, but from any device that is in my household. I get the same error from any device that I log into, with any roblox account I use.
This occurs with no matter what account I am logged into that has access to the game, and yes I have reinstalled studio. Once again, this is only occuring to one of my games, and this happens to be a game that I direly need access to at the moment for development purposes. Game link: 
Brainrot Brawl - Roblox
I have no beta features enabled.
This is the error I am generating:
