Character controller stuck in 3d space

As it says on the tin, I’m using a first person controller and its stuck in 3d space.

Until yesterday it was working fine, but since starting up today, the movement controls don’t work. I can still look around however.

Any help troubleshooting would be appreciated.

Thanks

Not sure how, but time scale was set to 0. Setting that to 1 fixed it.
Thanks for your input!
