frustrated as hell with imessage

iPhone 17 Pro Max on iOS 27 Dev Beta

I have a 3-person GC: one Android, two iPhones (including myself). It worked fine until the other day, when it randomly created a second gc without our chat name, then suddenly the messages they sent were sent to me in direct messages instead of the second chat, and then it created a seperate chat when i sent a message with the name of one of the gc members on top, and i cant type in that chat since theres no keyboard? What type of bug even is this, and how do I stop it
