Mine crashes, too
I can compose a message by pressing and holding the icon on my home page. When I enter a name, I can see the messages between us, and can send a message.
But like you, whenever I attempt to simply open Message, it immediatly crashes.
Any help would be appriciated.
I have tried everything short of unistalling and reinstalling. My daughter is in the military and I have some messages there I DO NOT want to lose. Any thing else I can try? or can I back it up? I still recieve texts and can reply as they show up on my lock screen. I just can't get in to the app or start a text.
I tried uninstalling and reinstalling, but the app still crashed upon opening. It all started for me after the most recent update, which occurred yesterday (7/31/19).
You won't lose your messages if you perform this action. Your messages will even transfer to other message apps should you choose to switch (which I have).
