Not sure if anyone is still having this issue. I am using a CORSAIR M65 ULTRA Wireless.
I believe this is a problem that comes from the crackdown on mouse drivers, macro software, etc. that people are now using to cheat.
FIX:
-I had Razer synapse installed, uninstalled.
-Ended task on iCUE and all related tasks (Logitech, iCUE, Synapse, Afterburner, SteelSeries)
-Launch Valorant
Keep on mind that your macros, lighting effects and DPI switches (on some mice) will no longer be functional.
I will forever express my disdain for this infectious and invasive anti-cheat. BOOOOOO 🤓
