Had the same after v4.18.209 update. I have got back to sync after some reinstalls and quirky sequencing. But likely will break again.

v4.18.209 update broke my Vengeance RGB Pro. It is fighting with ASUS Armory Crate hardware settings. I have uninstalled all and reinstalled in the correct sequence, but the settings are still fighting against each other.
