[Q] Can't receive picture texts / messages / mms, trying to send one crashes app

So yeah, as of recently I can't receive picture or video texts / messages / mms, trying to send one crashes the Messaging app

I've tried changing my APN to IPv4/6, resetting it default, as well as clearing Messaging cache, rebooted and no change.

I'm on a Nexus 4 Stock running 5.1.1
