iPhone 11 Messaging App crashing

Hi. Recently I’ve been experiencing problems when trying to write an SMS on my iPhone 11. As soon as I start typing the app crashes out.

I've tried all the suggested fixes such as force closing app, restarting phone, deleting old messages, switching iMessage on and off. I’m also on the most recent IOS update 14.6. Nothing obviously has worked.

I've stopped short of doing any resets as naturally that would involve a bit of work !!

It's really infuriating not been able to use SMS.

Can anyone help?

Thanks
