You're not alone. Similar problem but RGB on the I/O shield just cycles and won't allow control. I bought a brand new stock Asus ROG GA35DX gaming desktop with the same mobo and I/O shield in it back in ~2020. It NEVER would interact with Armoury Crate or AURA until last month (JAN 2024) out of nowhere after an update. BUT THEN... Armoury Crate and/or BIOS updated again (can't tell which one caused it)... it killed the ability to interact with the I/O shields RGB again and its back to color cycling while the rest of all my lights can be controlled. I'll never be able to track down what made it work and trust me, i was troubleshooting this for MONTHS when I first got the machine, I've essentially given up and ASUS Support is useless. For you, I'd check the BIOS, look for AURA setting and make sure it says ALL LED ON or ALL ON (can't remember), should restore your stuff.
