Game Center unavailable in iOS 13.1.2
Hi! Game Center on my iPhone XS has become unresponsive. Any game dependent on Game Center login fails to work. I tried checking the Game Center settings from the phone's Settings app. That too does not work, i.e., it freezes the Settings app.
Tried changing the network, restarting the iPhone -- both software restart and by pressing the buttons. All to no avail. I do not want to reset Game Center because game progresses (hard earned!) will be lost.
My phone's operating system is iOS 13.1.2. Game Center did continue to work after iOS was upgraded to 13.1.2, but stopped working suddenly. I do not remember installing anything or changing any settings before it stopped working.
Any idea as to what's going on?
