Unfortunately, there is still an error popping up from the Chroma’s software. I recommend following the steps in that post from the staff. And yes, iCUE and Mystic have a conflict that other players have posted about on the Corsair forums – I don’t use these devices and don’t know how this issue presents itself. Seeing as your iCUE drivers crashed several times in this report, it’s possible when the game launches it looks like you have no peripherals to play it. However, I still think it’s more likely that you still have Chroma files floating around somewhere.
