Knockout Rose Bush Seemed To Die Overnight, Is It Really Dead?

I have a rose bush that seemed to die overnight. The bush is well established and appeared to be “healthy”. It bloomed, the leaves were good looking. Then seemingly overnight all blooms were dead and the leaves were brown and dried as if it hadn’t been watered in months. I have attached two photos, the live bush is planted next to the problematic bush.
