Rigidbody First Person Controller wont fall over

I am making a diving mechanic where you jump and flop with constraints unchecked, but when the constraints are unchecked the capsule does not fall over, and in fact stands up straight as it always does. How can I fix this
I am using the built in rigidbody controller because i am pressed for time and it works good :). Thank you

Are you use default Character Controller component with combination of Rigidbody component?
It will not work.

If you want to create Rigidbody-based character, you should delete Character Controller component, and use for example “Capsule Collider”
