Cannot see anyone and not receiving messages from ATC

Device: IPhone 12
Operating system: IOS 16.7.1

Hello, I don’t know what is happening, but I cannot see anyone, and I cannot receive any response from the ATC and every online members appear as Unknown.
And I received a violation for entering the runway without permission, so I guess the ATC can communicate with me but I don’t receive any communication from them.

just had this yesterday, best response for me is to leave
