iOS 18.4 beta no connection and not able to download apps

Since the last update to iOS 18.4 beta I have no internet connection anymore. It doesn’t matter where I am. Display mentions provider and 5G but I can’t use phone anymore. moreover I can’t download apps (for example teams) from app store

I have the same problem, when I'm on the move the phone changes the transmitter every few seconds, iOS 18.4 has broken something in this regard and the worst thing is that even iOS 18.1 has not fixed it in any way
