Character Controller Jitters When Jumping Next To Objects

What i did was to set the slope limit to 90 only when im jumping. When im walking it is 45. So when you press the jump button set the slope limit to 90. And when you land set it back to 45. Not the best solution but it works well enough.

Bump. I know this is an old thread but I have the same problem :(

Edit: Found a solution by changing your Step Offset value. Try setting your Step Offset value to something smaller like 0.1. When you jump up near an edge your Step Offset comes into account.

I set the cc stepOffset to 0 while in air. This works perfectly for me. Also fixed so the character couldn't jump higher than intended exploiting stepOffset near an object while jumping.

 isGrounded = Physics.CheckSphere(groundCheck.position, 0.1f, groundMask) || yBefore == transform.position.y;
 yBefore = transform.position.y;
 
 if (isGrounded)
     controller.stepOffset = originalStepOffset;
 else
     controller.stepOffset = 0;

I know this is a very old thread, however I've been having this issue for years. I fixed it with the answers above, by setting my step offset to zero when I'm in the air and back to the default value when I'm on the ground.
