NavMesh Not Working, Not Showing Green

Hi All,

My NavMesh has just stopped working for no reason. It no longer shows green or red, and the AI can no longer use it.

I have tried dragging in a new one, deleting the old one, rebuilding and pressing P. I have also tried to restart to no avail.

Does anyone know why this could happen, and what I can do to get my navmesh back?

It seems to work just fine in a brand new project.
