if its still an issue try this.
on my corsair void wireless, i had the same problem. after trying a lot of things that you already tried i thought let's just try forcing an update (even though i already had the latest update) somehow this fixed it for me. so open your corsair utility engine and click on the gear sign for global settings then click on the update button next to the name (an arrow down pointing to a line ) and you will get the option force update or update from image. click force update and see if that helps.
