Why won't my phone attach anything to my messages?

[AC Question]

First off, I swear this is different from the others. I'm led to believe this is a phone problem not a network one. Anyways, I have an HTC One M7 and it has been working fairly well (not counting its inability to connect to most things/sync/get rooted/charge/etc), until I updated my phone last night. Since my update to 4.4.2 my Messages have been wonky. I am able to send texts and all that just fine...but anytime I wish to attach anything to a text this is what happens. Lemme walk you through the process:
- Open messages
- Pick contact
- Click attachment icon
- Select/take picture/video to attach
- Reads "Please wait..."
- Brings me back to album menu, hasn't attached anything
- Click back arrow or button, and find myself back to msg home screen
- Go back to contact's text, notice nothing has been attached
- Complain
- Try clearing caches, resetting, connecting to dif networks or just wifi/data, and so on
- Complain more
- Try to troubleshoot
- Aaaand here we are, with more complaining

So I feel pretty medium about this update, it looks fresh, has some different things, but it's not worth it if I can't do something basic like that.

I'm really hoping there's something super obvious that I missed so I can just be flamed a bunch but have my problem quickly fixed. Any and all help will be much appreciated!

Thanks,

Greg
