Character Falling ... Not a clipping issue just Character falling over

any idea whats causing this issue, i spent enough time in the past figuring out why the character models werent clipping with the floor the terrain etc, now ive developed a new issue, im gonna call it drunken male syndrome. Ive turned every option in the rigid body and the colliders on off sideways with no joy i know its something simple but for the life of me i cant see it

any help will be appreciated
