How to fix blank messages app

My messages app has been blank for a few days now, and at first it was on the beta version of ios, but now ive gone to the public 11.4 and it still persists.

I've force closed messages, cleared the cache, restarted my phone (iPhone 7), soft reset, reset all settings, turned iMessage off and on again, and updated my software. The only other thing i can think to do is back up, factory reset, and restore; but i would like to avoid that as I've had two incidents with that in the past.

I still get notifications (although not all the time for some reason), the messaged app shows a 2 plus however many notifications i havent seen on other devices, i can still see and send on my watch and connected ipad, i can send using siri, 3d touch on messages only shows create new message, creating a new message (from 3d touch or messages) and putting someone's name in displays an unknown at the top,

3d touching a notification is blank, and going to a notification brings me to the blank messages page.
