Character falls through ground with new animator controller

I created a new first person character with a new animator controller. When I hit play, the character falls through the ground after a few seconds and gets caught on the camera collider I think, so not fully through the ground. I'm new to rigged character setup, but the character is a rigged humanoid. It doesn't have any animations however, could this be the reason?
 
Hi!

If you're new to this, I'd recommend spending some time watching some of the videos from this playlist, in particular the setup, Character Creation and Animator Controller Structure videos:

It's also always a good idea to refer to the demo scene for issues and compare your setup with how the demo scene is set up. For example, does your character have a Rigidbody attached and properly configured? What about colliders? (Expand the Nolan game object in the demo scene and look at the Colliders objects.)
