It takes a long time for the Idle skill to be enabled.

I use the code, to enable the ability:
var characterlocomotion = player.GetComponent<UltimateCharacterLocomotion>();
var quieto = characterlocomotion.GetAbility<Idle>();
quieto.AllowPositionalInput = false;
quieto.AllowRotationalInput = false;
characterlocomotion.TryStartAbility(quieto);

I use the code, to disable the ability:
var characterlocomotion = player.GetComponent<UltimateCharacterLocomotion>();
var quieto = characterlocomotion.GetAbility<Idle>();
quieto.AllowPositionalInput = false;
quieto.AllowRotationalInput = false;
characterlocomotion.TryStopAbility(quieto);

I set StartDelay to 0 so the ability won't take long to start, but this doesn't work for me.

Check that there aren't other abilities higher up the list that are active and blocking it.

But this isn't really what the Idle ability is intended for. If you're trying to disable character input manually, you can use the OnEnableGameplayInput event, as described at the top of this page: https://opsive.com/support/documentation/ultimate-character-controller/input/
