Hello, casmith07!
Welcome to the Apple Support Communities. It appears that you're getting a black screen when you try to create a handwritten message on your iPhone. I am happy to help you get this cool feature working again.
First, try tapping the keyboard symbol in the lower right corner while the phone is turned sideways (this brings up the keyboard for typing), then tap the iMessage squiggle icon button in the lower right to bring the handwriting screen back.
If that doesn't fix the issue, try restarting your iPhone:
Restart your iPhone, iPad, or iPod touch
Let us know how it goes.
Have a great day!
