same thing happened to me it has been 2 days and i have deleted valorant, reinstalled it, tried running it with administrator and resetting my controls to the game defaults. My scroll wheel works outside of valorant but does not work in any gamemode in valorant. Im able to switch between my weapons with my keyboard by pressing, 1,2 and 3 but for some reason the scrollwheel on my mouse doesnt switch between the weapons. I also tried restarting my mouse by disconnecting it but still it does not work.
