After jumping, player can "stick" to object above him for a short time

Hi! I am a beginner at Unity and would love to work on this issue. Would be great it's assigned to me.
Thankyou.

Huh, I thought this had been fixed by Pull Request #16? Is it the same issue? Still happening?

Same issue, #16 solved it partially, but it still happens in some cases.
@Quickz 's solution:

private void OnControllerColliderHit(ControllerColliderHit hit)
    {
        if (isJumping)
        {
            // Making sure the collision is near the top of the head
            float permittedDistance = characterController.radius / 2f;
            float topPositionY = transform.position.y + characterController.height;
            float distance = Mathf.Abs(hit.point.y - topPositionY);

            if (distance <= permittedDistance)
            {
                // Stopping any upwards movement
                // and having the player fall back down

                isJumping = false;
                gravityContributionMultiplier = 1f;

                verticalMovement = 0f;
            }
        }
    }

Everything inside the if statement works well, the problem is with the condition. Releasing the jump button cancels the jump, which results in isJumping = false. Therefore, when the player cancels the jump before the collision and this function fires, the fix to the problem won't be executed. There are also other ways for isJumping to turn false, like when the time defined in jumpInputDuration is exceeded, and it would result in the same behavior.
What I suggested is instead of checking isJumping, we should check whether the character has any upward motion:
if (verticalMovement >= 0)...
Very trivial change, but this way, under any circumstance if the character hits a ceiling, the function would work as intended.

Shouldn't the isJumping bool get set to false once you are back on the ground I.e. you are done jumping. Would that solve the problem. I suppose I could explore all of the code relating to the jumping.

Oh, I see, good catch!! Seems like Quickz sent a quick fix. Let me check if it works.
