Same here (Z690-i).
Everything was working fine before the update.
I've tried uninstalling/reinstalling both armoury crate and ai suite. At first fanxpert started working. on next boot the error is back again.
i found solution from pornofesional on this site "reinstal windows". I think the answers from those "experts" are more insults than help. My friend bought Asus mobo too and the same problem with software and we cant find any relevant solution. Only problems but not some hardcore with overclock or ram power management . I just want use my fan curve and friend RGB both is f*ked up on asus.
