That would be your problem.
Is there a revolution target? If there is, and you can find a way to give them the CoR, then this is probably the quickest way to destroy the CoR and zeroise the revolution. (Give them the CoR, declare war with the crush the revolution cb, do not take the CoR in the peace, do use the special crush the revolution peace term.)
If there is a revolution target and you can't give them a CoR, or there is no revolution target, it's probably fastest to do the revolution disaster yourself. But you can only have this disaster once, and your post implies that you already had it, so this option may be irrelevant.
Otherwise, you need to crush the revolution target (using the special cb), and ensure that no new revolution target arises afterwards, and wait 20 years.
