If you don't have a third party anti-virus then no worries. For the firewall, head to your search bar and type: Windows Defender Firewall. Here go to -> Allow an app through firewall -> Scroll down to Valorant -> Allow private and public
@jidat if needed i can hop in a call and screenshare whats happening, because i dont know why but its not coming up with an error message, nor is it letting me uninstall valorant now from control panel
