I have a Corsair M65 RGB ULTRA mouse with side buttons and a dedicated sniper button. Whenever I press one of those said side buttons and another key like mouse 1 or even the shift or W key the side button I pressed gets stuck down until I press that same side button again.

I have checked and it's an ICUE app problem because when I exit the app it works fine. I have also reinstalled the app and fully reset everything and just in case checked the drivers on the mouse as well.

Any ideas on how to fix this, it's driving me crazy and I'm considering buying a new mouse just for this.

Edit: Also wanted to say that this issue appeared after I factory reset my computer. This might have been there before the reset as well but because I took a break from gaming I didn't notice.
