The player is stuck, is the Controller. SlopeLimit problems?

My question is like in the picture suggests, players in jump over obstacles, run into the ground, but because the point of view of the collision problem, the player was stuck, this kind of circumstance someone there solutions? Thank you for the first

No: slopeLimit is for ramps - you should increase CharacterController.stepOffset instead: this sets the max step height the CC can climb.
